Builders are having difficulty acquiring certain types of tower cranes, having to wait for them to become available or use a different more available brand or model.
However there are some clouds on the horizon. Crack downs by the Chinese government on money laundering and money leaving their country has put a stop to a lot of money flowing into new unit purchases. The Australian government (due to Chinese government pressure) has started to enforce foreign investment rules on real estate purchases instead of turning a blind eye and reaping the taxes as they have done previously. The big banks have already started to stop or reduce lending to foreigners for real estate.
I have observed on projects I am working on off the plan sales (pre construction sales) are falling with units now unsold at project completion. Not long ago I would see first hand units for an entire project selling out within a few hours of being put up for sale, before the first stages of construction even began.
Taxes being bought in on superannuation is inevitable. Both parties of government in Australia have announced they intend to do it after the election this year. This will hit property investment by diminish returns for investors who hold property in self managed super funds.
Regulation changes by the government have changed this financial year. Banks are required to hold a higher proportion of reserves to what they lend for home mortgages. This means banks will either need to find more depositors so they can lend or make less loans on their existing deposit holdings.
These factors aside there is an unnaturally high amount of construction going on, 288 tower cranes for Sydney, wow. In October 2014 RLB (the company that publishes that 'crane index') wrote an article called 'Skyline full of cranes' the number of tower cranes was 324 cranes... across the whole of Australia, with 119 in Sydney, and if you remember 2014 wasn't a bad time, no recession, construction was strong, no trouble getting work.
Even if construction doesn't crash but goes back to the average levels before the boom it will mean a lot of tower crane operators out of work (to fill the demand a lot of people have got work as crane operators and dogmen, when it falls back... these people have to go) and they will be either unemployed or working in jobs they performed before becoming crane operators.
Unlike other trades that constantly have work doing maintenance, renovations, extensions etc. the tower crane operator is dependant on new construction.
As for me when the work dries up I'm going to play golf... a lot of golf...
Ill have plenty of time
