Minister for Health, Natasha Fyles revealed in a press conference on Tuesday, August 17 that of those 300 identified, 65 were close contacts.

Ms Fyles encouraged anyone who believes they may have come in contact with the infected man to identify themselves.

"If you are a close or casual contact, you have done nothing wrong so please don't be afraid to identify yourself," Ms Fyles said.

"If you think you are a contact of this case, stay where you are and call our COVID hotline to make an appointment to get tested.

"People should only reach out to get tested if they are a contact or are unwell. If you are what we call worried well, you will burden our system."

To cope with demand, a pop-up vaccination clinic has been set up in Katherine to issue Pfizer doses.

"It's really important for people to take this time now to make sure that they, if eligible, get vaccinated," Ms Fyles said.

"We are receiving around eight and a half thousand new Pfizer doses from the stock that arrived in Australia on the weekend and Monday. They will be provided to Katherine and Darwin."

While there is yet to be another confirmed case of COVID in the Northern Territory, Ms Fyles said residents will receive updates should another be discovered.

"We have no more confirmed positive cases apart from the one individual but as those test results start to come through, we will certainly make sure Territorians have the information," she said.

The 30-year-old man, who entered hotel quarantine in Sydney after arriving in Australia from the United States, travelled to Darwin on August 12 before driving a hire-car to Katherine for work where he stayed at Knotts Crossing Resort on August 15.

He is now receiving care at the Centre for National Resilience.

"This person has done everything right. They had undertaken their 14 days quarantine but their day 17 or three days after leaving quarantine test came back positive," Ms Fyles said.

"There's been some commentary that he should've stayed in quarantine. We can only keep people in quarantine for 14 days. We have additional tests and he followed that direction."

The Katherine pop-up vaccination clinic is located at 19 Second Street.
