NSW Health has amended its latest health orders after receiving legal advice that they were "open to incorrect interpretation".
The new health orders came into effect on Wednesday after the government closed the NSW-Victorian border in response to the resurgence of coronavirus in Melbourne.
The NSW government will amend its orders to remove confusion around self-isolation requirements for anyone crossing the border.
A NSW Health spokesperson said the government's intent was to ensure anyone entering NSW from Victoria after the commencement of the orders would be required to self-isolate.
"The government's policy was not to be retrospective," the spokesperson said.
Victoria yesterday recorded the highest number of coronavirus cases in Australia to date, with 288 more people confirmed to have the virus.
NSW recorded 14 new coronavirus cases in the same day, 13 of which are in hotel quarantine.
