Jimmy,
Those Perth prices have risen that high because of the people in the present boom time earning over $100g a year,and eastern states investors moving in as Perth was cheap before compared to the other cities.
Lack of land put blocks of land up high ,lack of tradesmen put the cost of building up etc.
As for tradesman,yes they are all earning big bucks.The mining companies have trouble getting them now because they can make a big buck in the city ,so why head bush.
Give it a few years and things will change.
WA and QLD are the boom states---------Why-----------mining boom.
