No offence, but why not consult with Sub-Zero/Wolf and with an electrician, as opposed to asking about it here?
Sorry if that's coming off as a bit rude, but honestly you need to check with those parties regardless.

I hope it all works out for you. I'd be excited about getting that kitchen!

yeah , have done that twice, first time didn't want to know about it, second time reasonable but bottom line none non-committal.

The Wolf range you chose is a Dual Fuel and runs off
208-240 Volts (scroll down the left column once you open the link).

If Australia is 50HZ like Europe is, then you will have a problem with the clock and any timers. It is also "Possible" that the cooling fans within the range are rated for 60 Hz only at at the very least would run slower at 50HZ. You would unfortunately have to get that info from Wolf.

Most all US Fridges run off 120 volts, so you would at the very least need a step down transformer 240 to 120 volts and pretty large capacity too (amps or Watts). Again you could run into problems with the slower line frequency with the compressors motors & fan motors unless they are rated 50/60HZ.

Unfortunately Wolf/SZ keeps such a "Tight lid" on the technical info about their products that they are probably the only source for this info alto you can try Goggling
SZ compressor + model of fridge, and also do the same for evaporator fans, etc etc.

Sorry, it looks like this could be a bit of a PITA!

Good luck with it!
