Clarification: This afternoon it was confirmed that National Cabinet agreed to a nationwide stance on Greater Brisbane as a COVID-19 hotspot, with corresponding restrictions and quarantine or isolation requirements in place. However, the timing of the implementation of these new measures varies across different states and territories.
Governments from Tasmania and the Northern Territory have responded swiftly to Queensland's latest lockdown measures, setting quarantine measures for travellers who have been in the affected areas since 2 January.
Tasmanian Premier Peter Gutwein said the state had declared Greater Brisbane - including Brisbane, Moreton Bay, Ipswich, Redlands and Logan - a high-risk area.
Those arriving from these areas from today will need to quarantine immediately for up to 14 days, and if people can't find "suitable premises" they will be placed in a government quarantine hotel.
People who are already in Tasmania but have been in the affected Greater Brisbane areas since 2 January will need to self-isolate and contact the Tasmanian Public Health Hotline on 1800 671 738 to arrange a test.
The Northern Territory's approach is similar, with anyone entering QLD hotspots from today requiring hotel quarantine while those who have been in hotspots need to call the territory's COVID-19 hotline on 1800 008 002.
If that is your situation, you will likely need to be tested and physical distancing is required for 14 days since your arrival in the NT.
This physical distancing directive is defined by the government as "keep 1.5 metres away from others, if unwell stay home, sleep in a separate bedroom away from others, minimise contact with people".
