Tesla still has the network (both in superchargers and destination chargers). The main east coast routes are well covered in quick chargers but it's harder inland but improving rapidly.
In country areas caravan parks with 15A (3kW) outlets can be useful as well as place with three phase 32A plugs like showgrounds.
www.plugshare.com is the site for finding many of these outlets.
Also 3 months into my Model 3 SR+ ownership (the base model with closer to a 300-350km range that is RWD only), but yet to go further than Bathurst and Wollongong from Sydney.
It's probably useful to teach some terminology for anyone interested in electric cars.
Battery size is measured in kWh (like your electric bill). Charge rate is generally measured in kW.
In terms of battery size (some selected models)
Nissan Leaf 40kWh (older models 24/30/
Tesla Model 3 SR+ 55kWh
Hyundai Kona 64kWh
Tesla Model 3 LR/P 75kWh
Tesla Model X/S 70-100kWh (typically shown on badge)
Porsche Taycan 80-94kWh.
(At say 15-25c/kWh for home electricity or 40-45c for rapid chargers it also gives you a sense of the cost of a full tank. Even better if you can charge off home solar or an overnight tariff)
Then your charge rates (note that for consumer sockets you can only operate continuous loads at 80%).
Your typical 10A wall outlet is 2kW (240V * 10A* 80%). So would take 28-38hrs to fully charge a Tesla Model 3.
For single phase homes you can get a dedicated 32A circuit (7kW) or for three phase 32A (up to 22kW).
7/22kW is the typical speed of your destination chargers in shopping centres and hotels. Some of these come with a cable with a Type 1 or Type 2 plug (Type 2 is now the Aus standard) and others are BYO cable (and generally Type 2 plugs). Older Tesla DCs can charge other models if in legacy mode. Newer Tesla DC models cannot.
Then you have the limitations of the onboard charger (which essentially converts or rectifies the AC electricity into DC). This is 7kW in say the Leaf/Kona, 11kW in the Model 3/Taycan, 16kW in the current Model S/X.
Next you have the rapid DC chargers that supply direct DC current so bypass the onboard charger.
These essentially come in two models
Rapid (50kW) - most common in the NRMA / Qld electric highway rollouts
Ultra-rapid (120-350kW) - Tesla Superchargers (currently 120/150), Chargefox Ultra, Evie etc.
These are not cheap units and often require new powerlines/transformers so typically have a premium price of 40-50c/kWh.
Also in order to manage heat and battery degredation DC charging operates to a curve (controlled by your car). Typically between 5-40/50% battery you will get max power, but then it will start tailing down quite rapidly.
So on a long journey to minimise charging time you actually want to arrive at a charging station with 5-10% (and possibly only leave with 50-70%).
Confusing? Maybe.
But you get used to it pretty quickly (and at least in a Tesla the in car navigation and battery management is great). If you're ever getting worried about range best thing is to slow down. Difference between say 115kph and 105kph is massive (like in a petrol car it's all down to drag).
If you're interest in an electric car but worried about long journeys I'd also recommend having a play around with
www.abetterrouteplanner.com which shows optimal routes for long journeys (for Tesla cars also turn on CCS chargers under detailed options)
But as offshore71 says the main benefit of day to day driving is always starting with a full tank.
Of course for normal day to day driving, all brands of EV have a huge benefit in the sense that you effectively have a "refueling station" in your garage at home, and if you wish you can start every day with a "full tank".
