Put it to KF, then transfer any unused points to VFF.
Granted you will need 5000 points min in one program, and then loose 35%.
Its the sectors that is a disadvantage for Aussies living overseas, esp if partners dont carry the VA code/where VA dont fly its own planes.
Disadvantage with KF, is miles live for 3 years only, non extendable (except due to covid) but if you cant do sectors, slowly you drop off the VFF status ladder, might as well gain a bit by getting VFF points via KF even if its a long hard slog!
