Education Minister Martin Dixon's spokesman James Martin told the Weekly a decision could not be made before the May budget.

He said rebuilding would cost millions of dollars so a decision on whether to proceed had to be considered as part of the budget allocations.

Mr Martin would not be drawn on whether the government was likely to rebuild Galvin Park or to fix problem buildings, saying a range of options were being considered.

School council vice-president Anthony Monahan would prefer a decision to be made sooner rather than later.

"We just want [Mr Dixon] to tell us what he is going to do to get [Galvin Park] to an acceptable standard for today's education. We don't want it just patched up. It needs to come up to today's standards."

Tarneit MP Tim Pallas has written to Mr Dixon, concerned that the government's stance means any work on the school cannot start until funds become available in July.

He also expressed concern about the department's removal of furniture and fittings from classrooms two weeks before the start of school because of a mould problem.
