Concerns were raised in November 2009 after the school's P&C learned a $2.5 million hall, funded by the Federal Government's $14.7 billion Building the Education Revolution program, would not seat all students.

P&C president Tracey Kirk-Downey yesterday posted an emotional appeal for help to Ms Gillard after various State Government officials failed to act.

Speaking on ABC Radio yesterday, Ms Gillard said infrastructure program issues could be raised with her department, but NSW schools should contact the NSW Audit squad.

Ms Kirk-Downey said a submission to NSW Auditor-General Peter Achterstraat in December, also sent to Ms Gillard's office, had proven useless.

"They told us they couldn't do an audit on a case-by-case basis and they would be conducting a review at the end of the year, which would be a post-mortem examination," she said.

She may find her latest letter to the Deputy Prime Minister also bears little fruit, after Mercury inquiries to Ms Gillard's office were redirected to a government website which lists the NSW Ombudsman and ICAC as the agencies responsible for complaints.

Ms Kirk-Downey also claimed the P&C had been blocked in their attempts to gain further information about the hall, to the point they were unsure if the building would have air-conditioning or room for a new freezer.

The Mount St Thomas project, along with more than 200 others in NSW, is managed by Richard Crookes Constructions.

Stakeholder manager Caroline Chalmers said plans for the hall were provided to the school principal, who was free to communicate details.

The mood couldn't have been more different at West Wollongong Public, where P&C president Kelly Judd said everyone was eagerly awaiting the completion of their new hall.

"We're very excited about it. It's been pretty smooth sailing so far," she said.

Mrs Judd's comments were echoed by Coledale Public P&C president Terry Dunning, who said months of discussions hadn't uncovered any concerns about a new library.
