A 25-year-old man arrived in Darwin on June 22.

The man also disobeyed CHO directions when he traveled to Gapuwiyak to quarantine. He was found breaching quarantine by trading at a makeshift store on July 1.

A 47-year-old man arrived in the Northern Territory from Victoria on Monday.

A 63-year-old man and 67-year-old woman arrived in the Northern Territory from Western Australia on June 26 . Both were found absent from their place of quarantine following compliance checks on Wednesday.

A 38-year-old woman breached mandatory quarantine when she was found absent from her place of quarantine on Tuesday and Wednesday.

Compliance teams continue to conduct checks on people who entered the Territory after the easing of quarantine restrictions, allowing people to nominate a place of quarantine rather than hotel accommodation.

Acting Commander Shaun Gill said, "People still aren't getting the message that their actions are putting the entire community at risk.

"The Territory now has a new case of COVID-19 so it is utterly unacceptable that the selfish actions of a few expose the public to potential danger.

"The Chief Health Officer's directions are in place to keep Territorians safe. If you are in quarantine, you must abide by the CHO directions. No excuse is acceptable."

The infringement penalty for an individual is $1106 and $5530 for a business.

NT Police and Environmental Health Officers continue to undertake compliance activities.

A total of 21, 831 compliance checks have now been completed and 110 fines issued.
