Your calculations are correct. The issue is that Tesla Superchargers are a bit expensive. Fortunately destination charging is much cheaper (~$0.30/kWH). I tend to use third party chargers when I can.

Does using supercharger actually save money for a road trip compared to petrol?

This is currently not the case with Tesla. Or at least the last time I checked stats from teslalogger vs amount charged from Tesla. They charge the for the net electricity put into the battery. Worth considering also if you are trying to price compare. In effect this means any aircon or battery heating is covered by Tesla.
That doesn't seem right to me. Of the fast charging networks out there right now, it looks like this:
| Network | Charge Rate | Cost |
| Tesla V3 Superchargers | 250kW | $0.55-$0.66/kWh |
| Chargefox 350kW | 200kW (for Teslas) | $0.60/kWh |
| Evie 350kW | 200kW (for Teslas) | $0.60/kWh |
| Tesla V2 Superchargers | 120kW | $0.50-$0.66/kWh |
| Ampol Ampcharge | 80kW (for Teslas) | $0.69/kWh |
| BP Pulse | 75kW | $0.55/kWh |
| Charging The Regions 75kW | 75kW | $0.40/kWh |
| QESH 75kW | 75kW | $0.30/kWh |
| NRMA 75kW | 75kW | free |
| Electric Highway Tasmania | 50kW | $0.55+/kWh |
| ActewAGL | 50kW | $0.50/kWh |
| Chargefox 50kW | 50kW | $0.45/kWh |
| Evie 50kW | 50kW | $0.45/kWh |
| Charging The Regions 50kW | 50kW | $0.40/kWh |
| QESH 50kW | 50kW | $0.30/kWh |
| NRMA 50kW | 50kW | free |
I'm not seeing two to three times the cost. The only ones that are less than half the cost of the Superchargers are QESH and NRMA.
(Also for Teslas charging from Superchargers is a little better than shown because Superchargers charge you only for the net energy put into the battery, not the gross drawn from the charger).
Chargefox is also significantly cheaper if you have NRMA membership. 48 c/kWh for 350 kW, and 36 c/kWh for the 50 kW. For CBR-SYD Chargefox is at Goulbourn, 50 kW isn't much slower than a congested V2 supercharger (e.g. Tesla Goulburn, 65 kW if sharing when congested).
The reason people pay extra for EVIE and BP is for the convenience off the highway without driving through Goulburn.

Thanks for your table. It's very informative
On the flip side, I mostly charge at QESH (30c/kWh) when I'm on the road. That is less than half the price of Tesla superchargers. Especially if you don't have a Tesla and have to pay the 79c/kWh rate.
Thanks for that. Guess EVIE and Chargefox (with NRMA discount) are my best options as I can't charge at home

Depends on your car. My Corolla Hybrid uses 3.6L per 100km on the highway. hard to beat cost there..
but comparing a Tesla to a Yaris is very different in term of running cost than comparing to V8 Mustang
It really depends where in NSW you call home. There are a lot of level 2 AC charging around which can be as low as 30 c/kWh or even free, it really depends on what is convenient for you and if you can work it into your routine. Level 2 charging is also more efficient for Tesla as you aren't wasting energy heating the battery.
The table is also missing Jolt they have either 25 kW (and soon 50 kW) DC chargers, 7 kWh free per day followed by 46 c/kWh.
Yes, I was deliberately only looking at nominally 50kW and above chargers because I don't think 25kW DC chargers are really competing with Superchargers.
I like the table, and I think it adds good discussion material, but some of those prices are wrong, out of date..
Chargefox sent me an SMS today, saying they are putting prices up. Isn't the devenport supercharger and some others $1 a kwh?
NRMA will likely be free for members. They appear to be going to a membership model. Obviously with EV's its unlikely people will need a fan belt on the side of the road in the future. They are looking at otherways of modeling their business.
Also NRMA bough Chargefox.

Also the 200Kw limitation on Tritium isn't shared by other EV's.. The 800v chinese EV's are coming, and they will charge faster than Teslas, on a bigger network.

You will find that ABRP always estimates conservatively (as it should), as you can see from the following thread I can do Sydney to Canberra and arrive with 29% (no hypermiling but sticking to the speed limit) : Model 3 RWD 2022 Efficiency - Canberra to Sydney
Real world, I've driven to Canberra twice and have had the hotel's permission to charge the car, meaning that I've always done the return leg for $0. Try getting your Canberra accommodation to fill up your petrol tank for free.
