The next stage of its phased reopening plan would see international skilled and student cohorts, humanitarian, working holiday maker and provisional family visa holders allowed access from 1 December. This has now been delayed until 15 December.
The reopening to travellers from Japan and the Republic of Korea will also be paused until 15 December.
The temporary pause has been authorised by the Australian government in a bid to ensure the country can "gather the information we need to better understand the Omicron variant".
