The damage is located in the basement of the multi-storey car park with large cracks apparent on three pillars in the south-west corner.

"There's quite severe cracking there, that's a major issue," building defects consultant Ross Taylor told the ABC.

"It's quite fair enough for people to have a heightened awareness, and then ask the question, 'Is this right or is this wrong?'" he said.

The damage has been brought to light almost a year after the Opal Tower at Sydney Olympic Park was first evacuated due to cracks there.

Since then, a number of other residential buildings have been found to have major defects, prompting the State Government to appoint a special Building Commissioner to try and clean up the construction industry.

The damage at Revesby was brought to light by an anonymous letter to the ABC titled: 'The Next Opal Tower?'

"Next to the last column, the most serious, was a lump of concrete the size of a house brick, sitting on the floor," the letter said.

"It makes me wonder, with all the infrastructure work going on at the moment, and more being planned, who is auditing the builders?"

The Revesby Workers' Club said it was aware of the issue and had already acted.

"As a result of building movement, the two materials are pulling against each other, resulting in cosmetic cracking," the club said in a statement.

"We have been advised there is no structural concern."

The club said remediation works were expected early next year.

Structural Engineer Paul Siewert said the cracking needed to be fixed.

"Defects like this are common in the industry and are usually a result of inadequate engineering details or poor experience with the contractors on site, or a combination of both," he told the ABC.

The car park is a popular parking space for people attending the venue, but also nearby shops and Revesby train station.

When contacted by the ABC, a spokesman for the City of Canterbury Bankstown said it appeared the council had not been informed of the damage, and that an officer would undertake an inspection of the site this morning.
