If contracts don't work to protect consumers than it is very important that people who have issues with their builders to tell others about their experience (factual stuff with evidence eg. photos), this way people who are about to sign are well inform before they sign the dotted line. As more people (especially gen y and gen x) who are more tech savvy with the internet, forums like this will eventually change the building industry as the old saying goes " knowledge is power".
Just hope people share their building experience whether good or bad, i certainly will when constuction start.
Too right what Australia needs is a Whirlpool of the building industry.
