The NSW government is coming under increasing pressure to address the issue of apartments that could be covered in highly flammable cladding.
The state government is yet to announce an inspection regime despite stating it would make a statement on the issue last week.
Premier Gladys Berejiklian's government is under pressure one month after more than 80 people perished in London's Grenfell Tower inferno on June 14.
Opposition Leader Luke Foley on Wednesday met with frontline workers in the fire protection industry and said standards needed to be improved.
"What I've heard is that NSW lags the rest of Australia when it comes to standards around fire safety," Mr Foley told reporters.
"This is truly frightening for both our residential building sector and our commercial property sector and standards have to lift dramatically and urgently.
"This ought to be a wake-up call to the NSW government."
The Labor leader said the state government had been under pressure for two years to audit flammable material in buildings but "no audit is being conducted".
It's feared up to 2500 buildings in NSW have highly flammable cladding similar to that on Grenfell Tower.
