We're definitely keeping an eye on house prices in Australia too. At some point we'll want to move back and my partner is worried we'll be priced out... I'm of the viewpoint that with prices as they are, it might be better to rent until something big happens and/or forever.
I think supply chain issues are mostly sorted out in the US, but obviously the flow on effects to other (further away countries) will continue for some time. I'm sure the US is happy to bully suppliers to ensure they get first dibs, and Australia just doesn't have that same sort of clout.
