The NSW Opposition has called on Premier Mike Baird to reveal the secret cost of the botched Learning Management Building Reform program – running behind schedule and over-budget.

During a budget estimates hearing yesterday, Education Minister Adrian Piccoli refused to reveal how much the government plans to spend rolling out the besieged system – despite admitting the figure had been discussed by cabinet.

Mr Piccoli claimed the figure – estimated to be more than $1 billion – was cabinet in confidence.

The hearing heard the implementation of the LMBR – which has an impact on everything from how the rolls are marked to how principals ensure power bills get paid – has been so problematic that some staff had taken stress leave.

It also heard one pilot school passed a resolution to opt out of the system.

The botched rollout of the controversial computer system has already cost taxpayers more than half a billion dollars - $90 million over budget – despite having only been rolled out to one in ten NSW schools.

“It’s time Mike Baird came in to fix his Education Minister’s mess.”

“The Baird Government is overseeing a computer software debacle that's already six months late, $90 million over budget and only rolled out to one in ten schools.”

“Adrian Piccoli has refused to reveal the true extent of this cost blowout for weeks – but NSW taxpayers have a right to know how big of a bill they’ll be footing.”

Quotes attributable to Wastewatch Chair Chris Minns

“The Baird Government has already spent more than $573 million on a lemon of an IT system that doesn’t work.”

“The LMBR program lurches from one disaster to another – we’ve seen staff take sick leave, principals forced to pay for things on their own credit cards and schools now opting out because they’re so fed up.”

“Mike Baird needs to front up and tell taxpayers how much more they’re forking out, and whether the education budget will be slashed to pay for it.”
