Minister for Better Regulation Kevin Anderson has revealed details about the financial help which will be funded through a no-interest loan to the Mascot Towers Owners Corporation.

He said residents of one-bedroom units will be entitled to $220 per night, those in two-bedroom units will be allocated $300 per night and $400 will be provided for residents in three-bedroom units.

The money will come from the interest made from the Government's Rental Bond Fund and a dedicated hotline has been set up through Fair Trading so residents can register and receive help as soon as possible.

"These residents have been in a terrible situation this past week or so," Mr Anderson said.

"I can't begin to understand what it would have been like to suddenly turn up to your home and not be allowed in, so we've been feeling for them."

"It's the great Australian Dream to have your own home and to be turned away from it, to be locked out of it, I couldn't begin to understand what that would have been like.

"We have been living and breathing this with these people who have been facing an extremely stressful situation, so we are very pleased to be able to help them."

Construction industry to face 'shake-up'

Residents were allowed back into their apartments on Sunday to retrieve more personal belongings after being abruptly told to leave the building just over a week ago when cracks developed in the basement level.

Mr Anderson told reporters that "there is no great cause for alarm" that other apartment blocks across the city could be facing the same issues.

"But if any resident or owner has concerns within their building they should contact their building manager immediately," he said.

However, he conceded he "couldn't believe" that there was no requirement for engineers in NSW to be registered.

"So we will be fixing that problem very quickly and a raft of reforms will be put in place to ensure people can get confidence back in the construction industry in this city," Mr Anderson said.

"We will be conducting the biggest shake-up of the construction industry that New South Wales has ever seen."

The NSW Opposition accused the Government of failing its responsibility for good regulation and oversight of the industry and to ensure the safety of residents.
