North West Regional Hospital ED on track for reopening

Meanwhile, the reopening of the North West Regional Hospital's (NWRH) emergency department tomorrow after a coronavirus "deep clean" is the top priority of Tasmania's Health Minister.

The NWRH and the North West Private Hospital (NWPH) were closed this week after coronavirus cases associated with the operations in the region escalated.

The hospitals were closed for a "deep clean", patients were moved to other locations and ADF medical staff were flown in to staff the operations.

Health Minister Sarah Courtney said her priority was to get the NWRH emergency department open and operating on Friday.

She said her second priority was to get maternity services up and running.

Ms Courtney said cleaning at the hospitals was continuing on Thursday

"We have experts working incredibly long hours to make sure clean is done properly," she said.

"I want that emergency department open ... [and I] want to ensure it is safe for teams going in there, as well as our patients."

Ms Courtney said extra paramedics were currently deployed to service the north-west, aeromedical support was boosted and maternity specialists were on standby until the emergency department was open and operating.

She said new cleaning contracts were also being finalised for ambulances in Hobart, Launceston Burnie and Devonport and that 40 to 50 paramedic positions were being advertised with a focus on assisting the north-west.

There were more than 200 coronavirus tests in the region on Wednesday, authorities said.

Prime Minister Scott Morrison said there had been a rapid local response to the north-west outbreak.

"The Australian Defence Force, the AusMat teams working together with state authorities have been working very quickly to contain that outbreak," he said.

"There will be other outbreaks in other parts of the country and in all states and territories we need to move very fast."

Australia's Chief Medical Officer Professor Brendan Murphy praised health authorities for their response to the outbreak.

"We've seen a small outbreak in north-west Tasmania recently, where very rapidly, a large number of cases appeared over the course of a few days," he said.

"It's been expertly handled by the Tasmanian health authorities and is an exemplar way of bringing an episode under control."

Between 4,000 and 5,000 Tasmanians were forced into two weeks of quarantine on Monday as part of the shutdown of the two hospitals.

Tasmania Police said it had conducted more than 2,400 checks on businesses and households required to be in quarantine in the state's north-west.
