The Aussies have to take this back to the judge, because its pretty obvious Novak lied when he stated on the form that he did not travel in the 14 days prior to his arrival.
I‘d say his whole catching every six months to give him a permanent exemption stinks to hell. He 100% should not have been allowed to even get on the plane here, he’s not an Aussie citizen. If the government don’t deport him, then it’ll just give legal challenges to the rules a very firm footing.
