NSW Deputy Premier John Barilaro has warned Mark McGowan his state’s hard border could have unexpected consequences, and that the WA leader’s COVID-19 lecturing could “bite him on the bum”. Key points:Yesterday, the WA Premier urged the NSW Government to try and “eliminate” COVID-19Mr Barilaro described Mr McGowan as “a goose”WA has enforced the country’s toughest border restrictions throughout the pandemicMr McGowan, the WA Premier, reignited an ongoing border feud with the Berejiklian Government yesterday when he said Australia “could rest a lot easier” if COVID-19 was eliminated in NSW.NSW recorded five locally acquired coronavirus cases in the 24 hours to 8.00pm yesterday — two of which were reported yesterday.Two of the other cases were from the northern beaches and one is linked to the Berala cluster in Western Sydney.The northern beaches cases are a man and a woman in their 40s who are household contacts and the case in Berala was a close contact of a confirmed case and was already in isolation.Yesterday, Mr McGowan claimed NSW’s strategy of suppressing the virus was out of step with the rest of the country.But Mr Barilaro today said the WA Premier was “offensive” and a “goose”.”He seems to like to lecture New South Wales … if he wants to be the goose, he can continue to make those comments,” Mr Barilaro told the ABC.Catch up on the main COVID-19 news from January 12 with our coronavirus blog.WA has consistently had Australia’s toughest border restrictions throughout the pandemic, and Mr Barilaro claimed the state’s hard-line stance could have dire consequences.”We’ve had COVID deaths in this nation but we’re going to have more deaths from mental health, from people being locked away in isolation, people not being able to reunite with family, and Mark McGowan, that’s actually what he stands for,” he said.”I’m happy to say that this morning and have a go straight back at him.”We’re doing a bloody good job on the eastern seaboard and why don’t you become a part of the rest of this country?” NSW Premier Gladys Berejiklian has consistently opposed border closures during the COVID-19 pandemic.(ABC News: Timothy Swanston)China’s ongoing trade war with Australia has impacted a range of exports including timber, beef and mining and Mr Barilaro warned Mr McGowan his state’s economy, which relies heavily on shipping iron ore to the global superpower, could suffer.”He’s relying on royalties from mining — gee, the way China’s going that may bite him on the bum,” Mr Barilaro said.”If he wants to be the type of Premier that works with the rest of us, great. But don’t lecture us.”What you need to know about coronavirus:NSW Premier Gladys Berejiklian this morning said she “couldn’t care less” about criticism levelled at her about keeping borders open and urged other leaders to remember “we are all citizens of Australia”.She said because of the confidence her Government has in its health system, it was prepared to make decisions other states and territories were not.”I don’t want a situation in New South Wales that exists in other states where there’s a lack of certainty, things are done very quickly without perhaps, the same kind of consideration we give in New South Wales and that’s a matter for other state leaders but I don’t want to subject our citizens in New South Wales to that,” she said.She said anyone who thought elimination was possible “doesn’t appreciate what the pandemic means”.Mr McGowan has come under fire after yesterday suggesting NSW was out of step with other states striving to “eliminate” the virus from the community.But Mr McGowan said it was just “semantics”. “The aim is to ensure there is no virus in the community,” Mr McGowan said.Acting Prime Minister Michael McCormack today told Channel 7 NSW was the “benchmark” for coronavirus management.”I think any criticism of NSW is very hasty,” he said.Ms Berejiklian issued a plea for more testing after only 14,700 were conducted in the last 24 hours.NSW Health last night announced several new venues that are associated with today’s new locally acquired cases.These include the Blacktown Workers Sports Club and other venues in Warriewood.
