Well, W.A. has not had the 4 sqm rule since June 6 - it was reduced to 2 sqm.
WA has this precisely because the borders are closed to areas with community transmission. McGowan made this quite clear and has implied that if he is forced by the High Court to open the borders the 4 sqm rule will have to be reinstated.
We're not talking about what offers the best medical solution anymore. We are now balancing decisions around the trade-off between different medical and economic scenarios.
The Federal CMO and his team have talked about a need to maintain the 4 sqm rule as borders reopen. This is a serious economic impost. Modelling here and overseas shows that to be in the order of 5% to 6% of GDP. In other words, adhering to the medical advice of the Federal CMO and his team would sink Australia into the biggest economic slump that anyone younger than 90 has ever experienced in their life.
If by keeping the borders closed you can remove that restriction, then there is clearly also an economic impost. Primarily on tourism businesses. But the economic modelling shows this to be of less impact than the above scenario - closer to 3% of GDP. An ugly recession, undoubtedly, but far more palatable to far more businesses.
There is a third option where we open the borders and ditch the 4 sqm rule, but keep international borders closed. Impact of closer to 1.5% of GDP. A recession, but a stock standard recession. But in order to achieve this, then we have to press on closer to eradication and take a further economic hit in the next month or two in order to set ourselves up for a lesser economic hit in the long run. Arguably the right time to make this call though with the Federal Govt effectively guaranteeing large slabs of the wage bills of employers until September.
The fourth option is we open up domestic borders, ditch the 4 sqm rule, but be prepared to sawtooth parts of the economy open/shut/open/shut as the virus grows and shrinks. ScoMo has previously said that this would be the worst of the economic outcomes.
We have to choose one. There is no option that sets every business back on a path to success nor grows the economy in the short to medium term. There's no good arguing that certain businesses are in jeopardy because there are businesses in jeopardy no matter what scenario they run with. The question is just the magnitude of the damage that will be done and to which sectors of the economy.
