Queensland are pushing to dramatically slash the number of international arrivals allowed into the country in the wake of quickly growing outbreaks linked to hotel quarantine.
It comes after the spread of the Delta variant of the virus is much faster than previous strains seen in Australia, leading to heightened concerns in a nation with minimal vaccine coverage.
In announcing a snap lockdown for multiple areas of Queensland, Premier Annastacia Palaszczuk said there needed to be a "massive reduction in overseas arrivals".
Victorian Premier Daniel Andrews has backed the call.
