A woman who travelled from WA to Darwin has been fined more than $5000 after authorities found she breached quarantine protocols by not isolating after getting a COVID-19 test.

Perth and nearby suburbs were declared as coronavirus hotspots earlier this week, legally requiring roughly 2,000 people who had entered the NT from Perth in the days before February 1 to get a COVID-19 test and self-isolate until results were known.

NT Police said the 53-year-old woman arrived on January 31, meaning she should have sought a test and quarantined until a negative result was confirmed.

Acting Commander Scott Pollock said the woman underwent the COVID-19 test, but they found her “walking around” an unidentified suburb on February 2 and not isolating at home.

Cdr Pollock did not mention the locations the woman may have visited while on her walkabout.

“It does not mean that you are free to walk around the neighbourhood once you have been tested,” he said.

“You must remain in isolation until you receive your results and do not put your community at risk.”

Mr Gunner also reiterated on Monday that the COVID-19 management protocols “is not just some advice, or a suggestion to isolate, it is a legal direction from the chief health officer enforceable by law.”

Perth was ordered into lockdown on Sunday after a security guard working in a hotel quarantine tested positive for COVID-19.

NT revokes Perth and surrounding areas’ hotspot status as of Friday evening

Travellers from Perth and surrounding regions will no longer have to quarantine when entering the NT, after the chief health officer announced he will revoke hotspot status for the area as of 7:30pm on Friday.

People who had been put in mandatory supervised quarantine earlier this week when the region was declared a coronavirus hotspot will be released.

“There have been no new cases of COVID-19 in Perth, the Peel Region and the South West Region of Western Australia since the original positive case was identified,” a statement by the NT Government said.

“The Western Australian public health response to contract trace and undertake a broad public health response including a full five-day lockdown has contained any spread and has prevented a COVID-19 outbreak to-date.”

Chief health officer Dr Hugh Heggie said he had been “keeping a close eye on the situation in Perth” and was satisfied it no longer posed a risk.

“I work closely with my colleagues from other Australian jurisdictions to assess the risk of any outbreak,” he said.

“This includes the extent of community spread, which in this instance has been nil to-date outside of the original case, and the public health measures undertaken including going into a five day, full lockdown which concludes this evening.”
