The four Delta 22kW DC chargers located between Norseman and Ceduna were crowd funded by the Australian EV community in two stages, the first two in early 2022 and the recent two in December 2023. Although nowhere near as fast as the hard wired DC chargers at locations such as Norseman and Streaky Bay in SA the Delta DC chargers are a reliable solution until government funded fast DC is rolled out from late 2024 onwards.

Despite proving to be very reliable the Delta chargers require patience and methodical following of the instructions or users will find themselves wasting valuable time. I’ve used these four chargers a combined total of 18 times in less than 2 years, heed my advice to save yourself a lot of frustration.
1. Only plug in when the charger LED screens displays “connect to EV”, plug in firmly and don’t have a stretched cable. 2. Check charging has started, if the car displays “charging stopped” unplug, close the charging port and reconnect when the charger displays “connect to EV”. 3. Once charging has clearly started check back in after 5 minutes, if charging stops it’s highly likely to be in the first 5 minutes. I’ve never had a charging session stop after 5 minutes but that’s not to say it won’t happen, if you have phone coverage use the app to check every 30 minutes or so. 4. Don’t sit in the car with the aircon running while connected to 22kW or slower charging, it consumes valuable power that should be charging the cars battery, if you want aircon comfort sit in the Roadhouse Cafe. 5. Be thoughtful how you park, all 4 locations are in areas with other activities going on, look around and consider if you may be blocking access and potentially getting your car scratched by a room service trolley. 6. If you’re planning to stay overnight DO NOT leave your car plugged into the charger ready for the morning, there’s only one charging option at each location, leave the charger accessible for other EVs.
Balladonia Roadhouse
Balladonia If you’re wise you would have charged to at least 98% at the Norseman 150kW DC charger (if driving east), every 6 minutes at Norseman saves you 30 minutes at Balladonia, and a few dollars. To speed up the process at Balladonia get the passenger to jog in to the Roadhouse Cafe and ask for the EV charger key while the driver parks around the back. Once the key switches on the charger the start up process takes approximately 90 seconds, a good opportunity to get shade on the car. At the end of the charging session and just before charging stops use your phone to take a photo of the kWh consumed on the Delta LCD screen, make sure the photo is readable for the Roadhouse staff. Don’t forget to return the key when paying for charging.
Madura Pass
Madura Pass Park in front of the rusty vintage car and request EV charging in the fuel shop, a staff member will wheel the charger in to position and instruct you where to park, if you’ve parked in front of the vintage car you’ll only need to reverse up a few metres. Payment is to the RFDS in the fuel shop. Opening hours are strictly 7.00am to 5.00pm AWCT.
Mundrabilla Roadhouse The Delta charger is located inside the accommodation compound on the western side of the Roadhouse building, in the middle of the day parking is easy but before 8.00am and after 3.00pm you’re likely to have to deal with vehicles parked in front of the rooms, it’s wise to reverse park so you won’t get blocked in. This charger is switched on ready for immediate use.
Nullarbor Roadhouse
Nullarbor Roadhouse The Delta charger is at the rear of the laundry on the western side of the building, reverse parking with the black water tank on your passenger side will provide morning shade as well as not block the laundry ramp. This charger is currently kept switched on so connection to the car is almost immediate. At the time of writing a fixed payment is made at the cash register and your receipt must be clearly displayed on the car dashboard whilst charging.
I hope this information assists you to have smooth and happy travels whilst crossing the Nullarbor.
In September of 2019, a few days after our long-awaited Model 3 arrived on top of a tilt tray truck in our driveway, we took the pristine Tesla on a 360 km family road trip from Perth to Hyden.
Although we had been a two PHEV family since April of 2016, this was the first time we owned an electric-only vehicle, also known as a BEV (Battery Electric Vehicle) or PEV (Pure Electric Vehicle). With no internal combustion engine generator to rely on anymore, we had our first experience of ‘range anxiety’ when the car began warning me to plan my next charge because “all known charging locations will be out of range soon.”
Not long after the car began prompting me to “stay below 105 km/h to reach destination”. Being a new car, I was not only keen to test it out and to see what would happen if I ignored the warning but I was also curious about this ‘range anxiety’ phenomena that was often cited in EV articles and YouTube videos at the time. I kept Autopilot set to 110 km/h and not long after the warning changed to prompting me to stay below 100 km/h and then to below 95 km/h.
When the projection chart showed we’d get to Hyden with just 2%, much to my wife’s and I think the kids’ relief, I lost my nerve and I put the car into Chill Mode and slowed right down to 90 km/h.
We ended up getting to Hyden with 4% or 20 km of range and immediately after arriving I plugged the car into a 10A socket at the Hyden Tennis Club.
I didn’t have much luck with getting access to the 3-phase 32A socket at the closed Visitor Centre and I couldn’t get through on the phone either, but I managed to find a 15A socket in the shed on our friend’s property where we were staying. As I was keen to show off the car and took our hosts along for a test drive, when it came time to go back home, we couldn’t leave until after 2 PM as we had to wait for the car to finish trickle charging on the 15A socket in the shed. Being a Performance (Stealth) Model 3, with roughly 73.5kWh of usable battery capacity, it takes approximately 30 hours to charge from 0-100% on a 10A socket and about 20 hours using a 15A plug.
What a difference one proper DC charger makes
Fast forward to December 2023 and Hyden has just become the 26th location to be commissioned on the WA EV Network. It means that we’re now in the back half of the rollout because when complete in early to mid next year, the network will consist of 49 much-needed EV charging locations averaging approximately 200 km apart all the way along the coast from the Northern Territory border to the South Australian border and also to Kalgoorlie.
With the WA EV Network marking it’s halfway milestone, I couldn’t resist taking the same car, this time four years older and with over 110,000km on the odometer, on the same Perth to Hyden road trip. Perhaps still traumatised from the last experience, my wife and the kids were more than happy to leave me to my own devices so I set out on my own this time and about four hours later I arrived in Hyden with 9% and plugged into the freshly commissioned Hyden 150kW Kempower unit (I was aiming for 10%). Only half an hour later I had gained about 300 km of range which would have been enough to allow me to head back with a top-up at Williams but I got chatting and before I knew it, another 20 minutes went past and the car was already charged to 100%. (Once the Brookton charger is commissioned next year, a 20 to 30 minute charge in Hyden will be enough to get to Brookton for a quick top up on the way to Perth.)
Four years earlier, we had no choice but to trickle charge for 20 to 30 hours, which is a little like pouring petrol through a clogged-up straw. Comparing the two experiences is night and day, it is like comparing a rabbit to a tortoise. In other words, it’s just not comparable. Think about it this way, compare going to the beach for 20 to 30 minutes versus 20 to 30 hours or going to the shops for 20 to 30 minutes compared to 20 to 30 hours or popping into work for 20 to 30 minutes as opposed to a marathon 20 to 30 hour shift. Doesn’t matter how you look at it, the two time frames aren’t even in the same ball park.
In case you’re wondering, even though Tesla may be starting to roll out 1 megawatt (1,000kW) V4 Superchargers or Megachargers to service its Semis, the power of most DC (direct current) chargers these days will range between approximately 50kW and 350kW, putting the 150kW Kempower unit a little below the middle of that pack. Although some of the newest EV models, such as the recently delivered Cybertrucks are capable of charging at 350kW it doesn’t mean that a 350kW charger would be more than twice as fast as a 150kW unit. The limiting factor is the current generation of EVs, which in Tesla’s case, top out anywhere between approximately 190kW and about 250kW, depending on the model and its corresponding battery chemistry.
For those who think that a 20-to-40-minute time period to recharge a car is still too long, I’d like to point out something that I discovered on my 17-day trip around Australia in the Model Y RWD, the slowest and shortest-range car that Tesla makes. While I was charging at the various roadhouses, as suggested by TOCWA (The Tesla Owners Club of Western Australia) Chairman Rob Dean, I began to observe other people refuelling their ICE cars. I can tell you that the notion that people refuel their ICE car in 5 to 7 minutes on a long road trip is a fallacy. Granted, while it is possible, it happens very rarely and while most people may stand by their car with their hand on the bowser nozzle for six or so minutes, they will very rarely hop straight back behind the wheel to drive for another four hours. Instead, they will repark the car and they’ll use the restrooms, grab something to eat or drink and stretch their legs for a while. It means that an average roadhouse stop takes 20 to 30 minutes which is about as long as a Tesla Supercharger takes to recharge a Tesla. In fact, when my brother and I together with both families drove two Teslas along the 900 km route between Melbourne and Sydney earlier this year, we only needed to stop twice and both times our cars were charged to 100% before our food even came out. (By the way, as illustrated in this article, the last 20% of an EVs range takes the longest to charge and is often unnecessary.)
As an aside, for those reading this article who don’t yet own an EV or for the single EV families who are thinking about replacing their second car, it may be worthwhile to note that we no longer manufacture the Falcons and Commodores in Australia and hence we have no choice but to buy what the rest of the world sells and whether by legislation or market forces, the whole world is going electric. It, therefore, won’t be long before there won’t be much of a choice. That said, with ICE cars representing old technology what do you think a second-hand ICE car will be worth in 5 or 10 year’s time? Probably as much as a Walkman or DVD player is worth today. It’s old technology and when the world moves on, the old technology that’s left behind always plummets in value.
Getting back to the WA EV Network, yes, we all wish the WA State government made available a larger sum of money so that, similar to NSW, we could have had a network with an average uptime of 99.95% with ‘chargers that just work’. In case you’re wondering, yes, you guessed it, I am talking about none other than the Tesla Superchargers.
That said, I think I echo the sentiment of most of the WA EV community, when I say that we are very thankful for this much needed and critical public infrastructure. Although, as mentioned, we would all have preferred a slightly larger sum of money but we are nevertheless not only thankful for the $21.6 million but we’re thankful for Synergy and Horizon Power listening to TOCWA (The Tesla Owners Club of Western Australia) and the wider EV community when it came to the design of the network. As a result, it means we have a fantastic network which is fit for purpose.
By exclusively utilising only the Combined Charging System standard using only CCS2 cables and Type 2 charging points instead of the discontinued and obsolete CHAdeMO connectors, we’ll have a network that is built for the present and the future instead of the past. It means we have reliable and much faster 150kW Kempower chargers on the grid-tied portion of the network rather than the 50kW alternative. It means that with AC backup chargers every location can charge a minimum of three EVs at a time. It means we have idle fees to stop EV drivers treating the EV charging bays as EV parking bays, we have a credit card payment solution, we have a resilient system than can operate in emergency situations when the mobile network goes down, we have some but admittedly not enough drive-through locations allowing for EVs towing trailers, caravans or horse floats to charge without unhitching. We have a great network.
We have a world class network second only to Tesla’s Supercharger network and once completed, the state government will have provided most of the backbone of this critical public infrastructure for the private sector to backfill, but there is one glaring omission and that’s the inland Perth to Port Hedland route along the Great Northern Highway.
As TOCWA Secretary Harald Murphy has identified, it doesn’t make sense to have a road network that only services some towns and not others it doesn’t make sense to have an EV highway that leaves out major towns and regional centres. It’s a matter of equity, it’s a matter of access, it’s about tourism and it’s just not right to ignore and forget about places like Mount Magnet, Meekatharra or Newman to name just a few. With the WA EV Network having reached its halfway point yesterday, and with the retirement of Bill Johnston, (who said “I’m not saying no” to the proposed addition), the incoming State Energy Minister Reece Whitby has an ideal opportunity to announce the extension to the network.
It should be noted that the blueprints for the WA EV Network came from University of Western Australia Professor Thomas Braunl’s 2018 report which proposed three options for the network. All three options, included the Perth to Port Hedland route along the Great Northern Highway and the projected cost was estimated at $18.9 million, $23.6 million and $28.9 million for the Minimal, Proposed and Extended options respectively. (These were 2018 figures, therefore, if adjusted for WA inflation (All Groups) these numbers would be approximately 20% higher at $22.4M, $27.98M and $34.27M.) For reference the WA State Government has invested $21.6M into the WA EV Network.
The inland route from Perth to Port Hedland will cost less than $5 million and it needs to be announced now while we have the processes and the human and other resources in place rather than starting again from scratch in one or two years’ time. (To put the $5 million figure into perspective, just one freeway onramp costs about $20 million. To put it another way, there are 137 local governments or councils in Western Australia and some of them spend $20 million on just landscaping in one year alone, whereas the WA EV Network is critical public infrastructure that will benefit hopefully all Western Australians for not just one year but for 5, 10 or many more years into the future.)
Please join TOCWA, AEVA and the wider EV community in calling on Minister Whitby and the WA State Government to finish what they started and to complete the WA EV Network thereby making EVs accessible to all Western Australians, irrespective of where they live.
The minister can be contacted on the following links:
Please note, this article was edited on 21 December 2023. The changes consisted of the inclusion of the paragraph quoting Professor Thomas Braunl and the accompanying map, which were inadvertently left out of the original version.
Pete Petrovsky is an active TOCWA (Tesla Owners Club of Western Australia) committee member and a long-time EV enthusiast. He placed a $6,000 deposit for a Model X (#39) in 2014 but when it came to taking delivery he couldn’t justify the cost, so instead, he and his wife decided to buy two PHEVs and wait for the Model 3. In March of 2016 they bought the Holden Volt and a couple of weeks later the Mitsubishi Outlander PHEV, and on the day it was unveiled, Pete ordered the Model 3. After selling the Outlander, in September 2019, Pete received his long awaited first Tesla, a Model 3 Performance. Despite still loving their Volt, Pete and his wife took delivery of their second Model 3 in December 2021 and a year later a Model Y RWD which two days later Pete drove around Australia in 17 days. In his spare time, Pete also runs the ‘Tesla Ahead of the Curve’ YouTube channel and is also a long-term Tesla shareholder. Pete can be reached on X @Ahead_of_Curve
Now that the WA EV Network DC charger at the Overlander Roadhouse is available to the public the biggest gap between DC charging on the Perth to Shark Bay drive is 228 kms, once the Billabong Homestead DC charger goes live that gap reduces to 182 kms. This makes the 848 km drive (to Monkey Mia) a comfortable one day drive during the daylight hours of winter, it also means a standard range model Y could drive that trip at the speed limit while keeping the battery level between 20% and 85%. Take note, there’s no harm to the battery by going below 20% the potential issue could be queuing at a regional DC charger with no sentry mode available.
Northampton WA EV Network DC charger
Below is a suggested plan for those in a standard range vehicle, if you have a LR or Performance use the same plan but with a lower charge percentage when departing each charging stop. Plan for 9 hours of driving plus 90 minutes of charging spread over 3 or 4 charging sessions.
Jurien Bay, peak charge speed 115 Kw. If your trip is on the weekend or holiday period depart early. Although this trip can be done in daylight hours a 6.00am departure will pay dividends at the first charging stop in Jurien Bay. Why? Because humans are ruled by their stomachs, it’s a sure bet that on a Saturday morning or School holidays the Jurien Bay chargers will have a queue while the passengers stretch out morning tea. Trust me, you really don’t want to get stuck behind a couple of short range legacy EVs trickle charging to 100%. Get going early and get ahead of the grazing sheep.
Geraldton and/or Northampton, peak charge rate 115 Kw. The next charging stop is Geraldton so 80% is plenty to cover the 200 kms. Once you get close to Geraldton you have a decision to make, do you bypass Geraldton and push on another 52 kms to Northampton DC charger thus avoiding some of the Geraldton traffic or play it safe and “Always Be Charging”? This is up to you depending on how busy you think Northampton could be, keep in mind Geraldton has the capacity to charge 4 EVs at once, Northampton it’s only a 2 EV site.
The drive from Northampton to the Overlander Roadhouse is the biggest gap of 228 kms, even at 110 kmh in poor conditions a standard range could still drive this on 65% battery but the trick here is to keep charging until the charging rate drops below 45 Kw, this will generally be at approximately 85% on a standard range battery pack. Why is 45 Kw important? That’s the average charging rate you’ll get at the Overlander on the WA EV Network 50 Kw DC charger.
Little Lagoon Shark Bay
The drive between Overlander and Monkey Mia may only be 154 kms but has caught out many impatient EV drivers in the past, it’s a sure bet that sometime after lunch a strong westerly will blow significantly reducing range, don’t get caught short, add 154 kms of range plus a 20% buffer so your not hypermiling into Shark Bay after dark.
Foot note: Lancelin has both Tesla Superchargers and a WA EV Network charger, this is an optional stop on the way north on potentially busy days or if you’re not in a hurry and don’t mind the total 13km detour. Be aware that if you take this option and bypass Jurien Bay you’ll need to add enough charge to drive 303kms to Geraldton.
