Any details of the clever people in WA, I just bought a PHEV in Melbourne and drove it home to WA. Made it with no spare but was a tiny bit worried. They sure do make big potholes in Victoria. The Nullarbor road was actually very good.
NB they sell an anti rattle insert for about $70 but you can pick up a similar product (and it fits and works) for $25 https://www.ebay.com.au/itm/284543803300
