Catholic school funding modelling suggests some of their schools could be worse off under the Federal Government's planned overhaul of the system, reports The Daily Telegraph.
This clashes with a Federal Government promise that no school will lose a dollar under its new funding model.
But some schools in the independent sector have put off building partly because of the uncertainty.
Both independent and Catholic schools are calling on the Federal Government to urgently release its final financial modelling to give certainty to schools, which remain nervous they could be worse off under the overhaul.
Federal School Education Minister Peter Garrett has said his Government is waiting for updated financial data, set to be released later this month, before talking to states about their share of the costs.
Recommendations made in the Gonski review have been widely supported but are estimated to cost an extra $6.5 billion a year.
The calls come as a national campaign for action on the Gonski - school funding - review was ramped up yesterday, with prominent Australians urging the federal, state and territory Governments to act on it.
But Queensland Education Minister John-Paul Langbroek has labelled "the Gonski debate ... a cruel hoax" because of the lack of relevant financial data supplied by the Federal Government.
Independent Schools Queensland executive director David Robertson said the current situation was frustrating, with details on funding changes usually provided two years ahead.
