The FWC has a lot more clout than anyone, they are the only ones who are a government recognised trade association, they are the only ones the government will turn to discuss future legislation and reccomendations regarding window cleaners.
The government looks to the FWC to issue best practice, the government doesnt do it, it adopts the measures taken up by the FWC, this happens in every trade, hence why trade associations are a powerful force.
Look at most of the government literature for window cleaners, most of it has been written by the fwc and adopted by the government, or has been produced in conjunction with the fwc.
The BWCA although a fantastic organisation isnt a "Trade Association"
