The couple spent 18 days in lockdown on board the coronavirus-hit Diamond Princess, and another 14 in a former mining camp near Darwin.

In total, it's been 45 days since they left New South Wales. And Mrs Donnelly said the hardest part of the quarantine was missing the birth of their first grandson.

"We're home free, finally," she said.

The Diamond Princess captain let the Donnellys access the internet so they could see a video of the newest addition to their family shortly after he was born, and gave them a teddy bear for their grandson.

"We'll just be glad to go home and see the children," Mr Donnelly added.

"Looking forward to getting back to normal. I haven't driven a car for 45 days."

The couple were also looking forward to taking off their face masks, which they said made Darwin's humid temperatures feel hotter.

Mr and Mrs Donnelly had nothing but praise for the staff on the cruise ship and at the Manigurr-ma residential village in Howard Springs.

But they said they felt the Federal Government could have done more to bring Australians home sooner.

Altogether, 45 people were tested at the camp, and eight of them tested positive for coronavirus.

Those who tested positive in the centre were medically transferred to their home states, and one man later died in Perth.

'A day of joy'

Australian Border Force Commander Colin Drysdale said the guests were happy to be heading home, and praised the mission as a success.

"There were almost 50,000 meals prepared, and nearly 1,000 maintenance requests finalised," he said.

"There's been on average 190 staff supporting the efforts on a daily basis here.

"This is a day of joy for them as well."

Australian Medical Assistance Teams (AUSMAT) mission leader Abi Trewin said it was great to be able to see passengers and staff sit together without masks.

"We're very proud to see everyone leave today happy and healthy," she said.

The NT's first case

Last night NT Health confirmed the first case of COVID-19 in the Territory community.

NT Deputy Chief Health Officer Professor Dianne Stephens said the 52-year-old NSW man travelled from Singapore to Sydney about a week ago, then travelled to Darwin from Sydney on Qantas flight QF840 on Tuesday.

"He almost certainly contracted the virus overseas," she said.

"He interacted with the community for a very short time — it is very unlikely that anybody has been exposed to the virus in Darwin."

Professor Stephens said the man went to Woolworths on Cavenagh Street for a brief visit after arriving in Darwin, and then to the Ramada Suites in Darwin City.

"He then found out that his travelling companion, who stayed in Sydney, was unwell and had tested positive for the coronavirus. Feeling unwell, he isolated himself," she said.

She urged Territorians not to worry.

"It is inevitable that we will have some outbreak of the COVID-19 disease, but we are prepared.

"We don't need to panic-buy toilet paper."

A sign outside Woolworths says a customer confirmed to have contracted COVID-19 shopped at the store between 3:00pm and 3:35pm on Tuesday, March 3.

The customer notice says the NT Health Department has advised that the risk to anyone who was in the store during that time was "very low".

"We have a detailed cleaning program in our stories every day and are taking all action required," the notice reads.

The customer notice advised anyone who was in the store that becomes unwell to contact the Health Department.

"Anyone with concerns or further questions should call the hotline (1800 020 080) or visit the coronavirus (COVID-19) information website," it said.

Hotel's concern over communication breakdown

Ramada Zen Hotel assistant manager Michael Anthony said the first he heard that one of their guests had tested positive to coronavirus was through media reports.

"A report was that the guest checked in on Tuesday, but that's not exactly the case, it looks like they checked in yesterday," he said.

"We've been going through all our records to find out who this mystery person is."

Mr Anthony said the hotel did not know what room the patient stayed in and was frustrated by a lack of communication by the NT Health Department.

The 'pandemic plan' for the Territory

Territory Health Minister Natasha Fyles said the NT Government had been planning for many weeks.

"We have a pandemic plan," she said.

"We also have a remote communities pandemic plan, noting that many Territorians live away from our urban areas."

On Monday, Royal Darwin Hospital will set up a pandemic clinic.

Both Professor Stephens and Ms Fyles acknowledged there were some unique challenges to delivering healthcare in the NT, such as a high population living in remote locations.
