Yes, you are indeed wrong
The new Torquay 350kW charger is the only ultra-fast unit charging at the moment. Euroa and Barnawatha are free. Best way to see this is to download the ChargeFox app.
Torquay and Airport West charge 40c/kWhr for both the 350kW ultrachargers and the 50kW. Euroa and Barnawatha are free as noted. If you look at the Details tab for each station in thew Chargefox app it will tell you what the cost of charging is for each station.
