The Builders Collective of Australia says it is worried that regulation and compliance are not strong enough in the nation's building industry.
The comment comes after safety concerns were raised over high-rise apartments in Sydney's west when residents say they saw and heard cracking in the 38-storey complex.
Residents of 51 units in the Sydney Olympic Park building remain barred from returning to their homes while engineering assessments are carried out.
The Builders Collective of Australia's national president, Phillip Dwyer, says the exact nature of the problem is still being worked out.
Mr Dwyer says he is concerned the building industry is currently facing significant issues.
Mr Dwyer says a 'she'll be right' culture of regulation in the building industry is a major concern.
Meanwhile, New South Wales Treasurer Dominic Perrottet [[PAIR-o-tay]] has commended emergency services' handling of the Olympic Park high-rise evacuation.
Mr Perrottet says safety is the government's key priority.
He says investigations will be held into this incident.
The developer of Opal Tower, Ecove, has issued a statement saying the builder, Icon, is well-established and a high-quality builder.
Ecove says they are waiting on further information from the engineers, but understand the problems concern a concrete panel.
They say it's important to note the authorities have deemed it safe for people to re-enter and they have isolated the issue to a small number of apartments.
