As VA is not flying a lot internationally using their own aircraft, (except Fiji), there is not a lot of options using their own aircraft, with a VA flight number flying internationally (far away).
They are even not flying to NZ.
With partners, yes, there are options in Business, but not so much in premium.
SQ does not have a lot of premium seating on flying out of Aust if you want to try their A350, they have premium seats on their A380 or B777, but you do need to phone up, though if you want to try online, I think that is not available at the moment, but have a look.
UA might be an option later on in the year.
Does EY have premium, haven't checked, but don't think so.
If you just need a get away, SQ to SIN might be an option, double or triple vaxxed, and do the covid PCR test.
They do not have a lot of partners flying regularly, SQ is not daily, they have their VTL flights.
If you want to reduce your VFF points balance, fly domestic would be an option.
NH might be an option later on in the year too.
