Police have issued 13 infringement notices for failing to abide by the Chief Health Officer Directions issued under section 56 of the Public and Environmental Health Act 2011.

A 58-year-old man in Alice Springs was issued an infringement notice after he left his quarantine location and was found at his girlfriend's house.

A 31-year-old man and a 26-year-old woman who had recently arrived from Queensland were issued infringements after police spotted them out drinking with friends in Alice Springs.

The man had earlier been cautioned by police after it was learned he had left his place of quarantine to take selfies at the top of Mt Gillen.

Nine people, between the ages of 21 and 42, were all absent from their places of quarantine in Darwin.

They were contacted by Police and were unable to provide a lawful justification as to why they were not quarantining.

A 40-year-old woman in Nhulunbuy was found to be hosting people at her accommodation.

Police attended the location and directed three people to leave the motel.

The woman was also issued with an infringement for consuming liquor in an alcohol protected area.

Acting Commander Shaun Gill said, "It will only take the actions of a few to ruin it for the majority of the community who continue to abide by the rules."

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.

The infringement penalty for an individual is $1099 and $5495 for a business.

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

A total of 19,923 compliance checks have now been completed and 96 fines issued.
