I received Australia visa after my UK refusal so should I reapply right now or after I come back from Australia? Currently I have only traveled to Dubai and Turkey.
Are you planning to go to the UK before Australia? If not - apply after you're back, you'll show that you've returned home from a visit to a similar country before.
If I am to reapply, should I apply as a lone traveler or should I mention my aunt? (considering that family ties in UK might count as a negative)
Lying is worse. They already know that you planned to visit your aunt.
Is there any other way apart from reapplying/Judicial review to fix this issue?
Unlikely. How important this trip was for you? If it's not critical - just try again next time you have time to travel.
