As long as Morrison sustain his staunch anti China policy, he got a good chance for another term. The general public is willing to take economic pains as long as his policy is aimed against China or at least not favouring China. He never criticised Trump/US which favour him now and in 4 years time when Trump is back as POTUS.That is going to be a hard task with Morrison support at historical highs 62%plus. I can see him staying in as PM for at least another term and with the Replublicans in with a chance to occupy the White House in 2025, who knows what's going to happen.
China's reliance on Australian ore for the intermediate term at least won't make it easy.
The success of controlling Covid virus also boost his popularity but this is due to state governments policies which are usually at odds with Morrison's federal government.
The opposition is a little more level-headed against China so they loss a lot of votes to Morrison. Yes, he will be around for a while and getting more confident ( not necessary competence).
