The Economist has just put out their "Big Mac" index of currencies relative over and undervaluation.
https://www.economist.com/big-mac-index You can adjust the variables yourself i.e. in PPP or GDP adjusted, However, it suggests the AUD is some 16% undervalued relative to the USD.
IMVHO, Over time the USD overvaluation relative to most, particularly Asian currencies can be expected to be corrected no matter the shenanigans with: money printing; interest rates; cryptos and sanctions. Gold is the equalizer. (Probably why the Swiss franc is overvalued too but it is no longer backed by gold- at all).
All IMVHO.
