Ok. Just trying to help.
With a quickish look I was able to find availability on a route FCL - DXB - SGN - NRT - MEL - SYD all J for 2 pax.
It will likely be more points than you have but there seems to be stuff all availability from Asia to Australia up to and including the 23rd /24th of July. I suspect school holidays? There is BA J availability from Sin to Syd on the 27th.
Identify the oneworld airlines (and EK) and using the QF website work backwards from different cities in Australia to their home ports in Asia. Once you’ve found a flight into Australia then the options for getting from Europe to that port are more varied.
The interactive map can be found on the one world website using the find a flight menu and then clicking on see where we fly
Good luck
