As an retired ex builder I think of the work I put in to become licensed and I have only one comment Australia's educations system is totally stuffed and IMHO it has been done deliberately
I am qualified in 0ther fields as well and I see a qualification that took me three years full time to get, that you can now get in two weeks part time
When I say it took me three years, it was a three full time course, you could take longer but no shorter
I see so called carpenters now that are unable to properly fit a door and they take hours and hours to do that
Now it could be that the bureaucrats do not know what happens when they mess with training, but I am unable to believe that they are all crazy as loons ---- so it must be deliberate
