Call your privilege club membership line as soon as possible and ask them if they can get you on an earlier flight. Be completely flexible on dates and destination, maybe even from tomorrow if they are flying.
All airlines are cancelling huge chunks of their schedules as is being widely reported. Partly due to no passengers wanting or being allowed to fly, partly because they can't crew many destinations now due to entry restrictions at those and subsequent destinations.
It's not really a question of rights in the current climate. If you want to get back you may need to travel asap or face sitting it out where you are, as many governments are now advising their citizens. Otherwise you may only be due a refund or future travel voucher, as would be the case even on a EU airline, since your booking appears to be outside of 14 days and thus EU261 would not apply (even if force majeure wasn't in place). If QR can't carry you you may have to stay put or pay another carrier who can.
