A 30-year-old woman who travelled to the Northern Territory from Melbourne has been discovered working in a store in the remote community of Ngukurr, in breach of self-quarantine orders.
The woman arrived in the Territory on June 16 after travelling from Melbourne via Brisbane.
Police said she has now been taken to Katherine to complete her self-quarantine and issued with a fine.
As reported in the NT Independent, NT Member for Stuart Scott McConnell called for the Territory Government to undertake widespread COVID-19 testing in Ngukurr now.
"This would be very inconvenient for the individuals concerned, but considering the level of concern around this virus in remote and vulnerable Indigenous communities, it is the appropriate action to take," he said.
Over the past week, Melbourne has seen an outbreak of Coronavirus cases, resulting in new restrictions and warnings to avoid travelling to the Victorian city.
A 47-year-old man and 54-year-old woman who travelled to the Northern Territory from Melbourne on June 19 will also receive infringement notices after police were informed they had attended a cruise in the Kakadu National Park.
The pair had been issued a work exemption to pick up a vehicle and leave the Territory but were ordered to self-quarantine while they weren't at work.
A 20-year-old woman and 41-year-old man were not at their homes in Darwin when self-quarantine checks were undertaken this week.
Northern Territory Police Acting Commander Shaun Gill said it was "extremely disappointing" to see people become complacent with self-quarantine orders.
"We are still in a health emergency situation, and the threat of COVID-19 returning to the NT is very real, even more so with the borders opening on 17 July," he said.
"Police are strongly urging people to abide by the rules in place and to not put other Territorians lives at risk, particularly our more vulnerable remote population.
"Travelling to a remote community when you are supposed to be in quarantine could potentially have a disastrous impact and devastate a community."
To date, 17,825 compliance checks have been completed and 75 fines issued. The infringement penalty for an individual is $1099 and $5495 for a business.
