It looks like Type 2 on the side shot, but you haven't given us a front on shot of the car end.. if so it's somewhat useless in the US, so selling to an Aus or NZ best.
The the 2nd issue is what generation the tails are. Newer ones are marked 15/15A and 10/10A, older ones 15/12A and 10/8A. The newer ones are 20% quicker to charger.
If it is Type 2, I'd recommend joining a FB Group - Tesla Parts Buy Sell Swap Australia (about 5k members) and advertising there, after working out what shipping costs to Aus are.
In Australia these new with the new tails are US$360 delivered, so you are going to need to be under that that to get interest (and I suspect shipping costs won't be that cheap)
