it is well known that Australia has an extremely lazy workforce that refuse to put in any real work.
the best example here is the stupid residential building cost. nowadays it costs over $1m AUD or $700k USD do a first floor 2bedroom 1 bathroom extension for an existing house in good condition. That is significantly more expensive than building a big house in the US.
let's don't even start on the quality of those new builds, that would be the laughing stock of the entire world.
