Quarantine requirement at government designated site. Unvaccinated travellers may be subject to quarantine requirements in the state or territory of arrival. You should check requirements for the state or territory in which you will arrive.
Quarantine and self-isolation rules after entry into Australia are managed by state and territory authorities. Some states require partially vaccinated or unvaccinated children aged 12 to 17 years to self-isolate even if they are accompanied by fully vaccinated adult travellers.
If children are accompanied by unvaccinated adult travellers, the entire family group may be required to quarantine and will generally be subject to passenger cap limits for unvaccinated travellers. Travellers should always check the requirements of the state or territory they plan to travel to, or transit through, prior to arranging their travel.
