Before we all get too carried away and angry about those sort of pay levels it’s worth remembering that qualified trades in this country are literally Koala Bears politically. Both sides of politics protect them from any sort of labour competition that is why there is a skills shortage and they are now looking at pay levels 2-3x minimum wage. Neither the Libs or Labor will allow any sort of skill migration for skilled labour and that is why construction costs are astronomical and Unionised Labor are getting these sort of deals. No other country in the world would allow that to happen except in Australia.
The issue this generates is that it destroys the incentive for any sort of educated job. Why would you go to Uni, incurring decent amount of debt when you get paid management level incomes to work a trade? Or worst still spend 150k to be a pilot to earn minimum wage type of salaries. Honestly what’s the point? It’s even worse when you look at how this affects qualified white collar jobs in the building industry.
