Dan mentioned this in another thread that it's the draconian bio-state causing stress on the hospital system - more than Covid. The same is true in all industries currently in Australia.
It was one of those things that was never going to work - quarantining close contacts when you've got 10k cases a day and spiking (it's now over 100k per day). That's up to a million close contacts.

Sure some can work from home - but you can't work from home if you're a truck driver delivering groceries to supermarkets. Or fuel to petrol stations.

The level where Covid (a covered-up lab-exit!) could get truly scary is when there's not enough food on the shelves.

Scott Morrison: The more you try to protect your hospital system, the more people you are taking out of work, which disrupts supply chains.

Well you're the one who introduced the rules buddy. He's furiously back-pedalling now that over 10% of the workforce are off on any given day.

This is a constant daily process of balancing the need to keep people at work and to protect our hospitals. And that is why it changes almost daily.

Guess that's the alternative system of government to thinking things through first.

If there's a crash it will probably be this year some time. Likely a perfect storm event with a range of things compounding the situation. Labor shortage could easily be one of them. When demand is greater than supply, prices go up - whether its goods or labor.
