While, Victoria's DHHS has advised arrivals to stay home and get tested.

The new NSW order not only applies to people yet to enter the state, but those who have arrived in NSW from January 2.

It comes after a Queensland case of COVID-19 was confirmed to have the more transmissible UK variant of the virus.

On Friday night, the state government announced residents or travellers to NSW, who visited any of the eight local government areas in Brisbane must go directly to their home or accommodation in NSW and remain there until 6pm on Monday.

This includes the City of Brisbane, City of Ipswich, Lockyer Valley Region, Logan City, Moreton Bay Region, Redland City, Scenic Rim Region, and Somerset Region.

Although those who have arrived in NSW after transiting through Brisbane Airport will not be subjected to the same rules, granted that they have not been to the listed areas.

The state government stated that Queensland arrivals will be allowed to leave their home only to obtain food or essential shopping, exercise or to perform work duties if they cannot be done from home, caring duties or medical care.

Anyone who has been in the Greater Brisbane area since January 2 cannot visit people in aged care or health care facilities in NSW.

People coming to Greater Sydney from Queensland have been reminded of the need to wear face masks in certain situations, including while shopping.

All people arriving in the state from Queensland by air must also complete a self-declaration form, with their name, address, where they stayed in Queensland and dates of arrival and departure.

Enforcement officers will have the power to require information and identification documentation to assist in checking compliance.

Travellers from Queensland have been urged to monitor for even the mildest of symptoms and immediately get tested and isolate if they develop.

Once tested, you must remain in isolation until a negative result is received, in line with the normal advice for all people in NSW.

Victorians in Queensland can apply for transit permits online, but have been issued with new advice due to a lockdown of Brisbane.

"All Victorians in these areas are advised to follow the guidance of the Queensland Government and any Victorian with plans to travel to these areas should cancel them," DHHS said.

"National Cabinet has declared Queensland a national hotspot after the discovery of a UK variant of COVID-19 in a cleaner at a Brisbane quarantine hotel.

"Those who have arrived in Victoria from these areas since 2 January should get tested and remain at home or place of accommodation until Monday, when a further assessment will be made.

"The border with NSW remains closed and the department is working though more than 4000 exemption applications. 579 exemptions have been granted so far and staff are processing the most urgent cases first with priority given to Victorian residents."

AWH's Leisa Bridges said following developments in Queensland, AWH was "urging any returned travellers who visited a COVID-19 exposure site in Brisbane to get tested immediately".
