Bushfire Response Minister Peter Ryan said the positions were cut to reflect the reduction in demand for the advisers. However, fewer than one third of homes destroyed on Black Saturday in Whittlesea have been rebuilt and have an occupancy permit.

The cuts have angered the Whittlesea Community Recovery Committee and the Whittlesea council. WCRC chairman Larry Challis said Mr Ryan's actions were "dismissive".

The five rebuilding advisers were experienced construction managers who advised residents about permits, designs, contract issues and local contractors.

The rebuilding adviser for Kinglake, Whittlesea and the surrounding areas finished his contract on December 31.

Mr Challis said the cuts meant knowledge and contacts developed after years of experience in the community would be lost.

"It's only a couple of positions but it's a really big issue in the region," he said.

Mr Ryan said on 774 ABC in December that extra positions would be added if needed.

"Should it be that there is a demand demonstrated for those additional personnel, then we will make them available," he said.

Mr Ryan denied the cuts were part of broader cuts to the public service.

Of the 76 Whittlesea houses destroyed in the fires, only 24 have been rebuilt and have an occupancy permit. The remaining 52 have been issued planning permits but building has not yet started.
