I'm not even close to any of the economics or the respective industries however from various media reports and political maneuvering over recent months I will speculate:
I think chinese student market is fairly well stuffed regardless of travel bans, covid etc with the CCP, by series of a thousand deliberate cuts, is slashing the volume of yuan coming Australia's way; students included with wine, beef, iron, tourism, etc generally. Chinese tourism was a major component of our hospitality industry pre covid and I am of the opinion the CCP with be throttling that with any & all tools at its disposal until there is a major improvement in international relations. In addition to that, the abandonment of student support by all governments in AU during the pandemic has resulted in a huge backlash on social media in China against the country and we no longer hold the same favoured destination status for education
India has a long way to go with the pandemic and the flow of students from there could slow dramatically regardless of border issues, particularly as the Indian economy is damaged and those from families that were "just managing" the costs before are impacted. Quarantine costs in and out combined with the current airline rip off fares may hammer the nail in the coffin for many thousands.
Domestic tourism possibly could surge once the internal borders are sorted with significant pent up demand making up for a large proportion of international visitors.
A bubble with NZ and the pacific (depending on quarantine rules) would be more beneficial to AU than anyone else and be revenue positive to AU.
