Pandemic could have killed 30,000 in WA: Premier

Premier Mark McGowan said the crisis in WA was far from over, despite the low number of cases.

"This is a marathon, not a sprint," Mr McGowan said.

"Even though the numbers in WA are promising … we have no reason whatsoever to get complacent now."

Mr McGowan played down the prospect of social distancing restrictions being eased due to the limited spread of the virus.

"The advice I am giving everyone is to look forward to a hard, long six months," the Premier said.

The WA update came on the back of modelling released by the Federal Government, outlining what may have occurred had social distancing rules not been enacted.

Mr McGowan said the modelling showed up to 30,000 West Australians could have died if nothing had been done about the virus.

Mr Cook said the slowed growth in COVID-19 cases in WA meant the state was now expecting the crisis to peak much later in the year, citing November as a possibility.

"A long, flat curve is much better for the community than a sharp, high one," he said.

Second death from Artania cruise ship

The latest death from the Artania is the second fatality from the vessel in WA in just a few days, with cases from cruise ships now making up 36 per cent of coronavirus infections in the state.

"It must be incredibly difficult for their families on the other side of the world," Mr Cook said.

"We extend our condolences to all involved."

Federal Attorney-General Christian Porter has defended the Commonwealth's handling of the Artania, which remains docked in Fremantle.

The vessel, which had no Australians on board, is responsible for about 50 cases of coronavirus in WA hotels and hospitals.

The WA Government had been agitating for the vessel to leave urgently, but Mr Porter said an appropriate compromise had been reached.

"There has been an appropriate balance struck, in terms of looking after the individuals on these ships regardless of their nationality, but also ensuring there was proper quarantine," he said.

"There will be some tensions along the way but it is about finding the right balance."

Mr McGowan also confirmed 235 exemptions had been made to allow people into Western Australia since the state's interstate border was shut on Sunday night.

A total of 70 people have been allowed in by air and 165 by road, while two people have been sent back.

Three on-the-spot fines of $1,000 have been issued over the past few days to people not obeying social distancing and travel rules.

Another eight people have been issued with summonses and will be dealt with by the courts, with anyone found guilty facing fines of up to $50,000.

Year 12 exams likely to go ahead

The Premier made no new announcements about whether WA schools would be open next term, or about the fate of ATAR exams for Year 12 students.

He said any decisions would have wait until Thursday, when federal and state education ministers who met today would provide a report to the National Cabinet.

But Mr McGowan did say as far as the WA Government was concerned, ATAR exams would proceed this year.

"It would have to be some sort of disaster to prevent that occurring," he said.

"It may mean that exams are later in the year, it may mean that courses are reconfigured to reflect the shorter time period that students may have to study.

"All of that work is being done, but ATAR as far as we're concerned is going ahead this year."

Parliament to debate urgent legislation next week

Meanwhile, the Government has confirmed plans to recall State Parliament next week to pass urgent coronavirus-related legislation.

MPs have been told the Lower House will sit next Wednesday and the Upper House on Thursday, to consider more measures to deal with the impact of COVID-19.

Among the items expected to be on the agenda is the use of Lotterywest revenue as a support fund for not-for-profit organisations, exemptions for payroll tax related to payments from the JobKeeper scheme and changes to commercial tenancy arrangements agreed to by national cabinet.

Mr McGowan said commercial rents "would need to come down".

"Commercial tenants have had revenue collapse, commercial rents should reflect this," he said.

"I don't want to see any tenant lose their business and then be sued for their house just because they cannot pay their rent during this period."

Mr McGowan said the Government was also "assessing options" to provide land tax relief, but no commitments had been made.

State Parliament will again be subject to strict social distancing measures for its recalled sitting, with more than half of Lower House MPs told to stay away from the chamber last week.
