Cr Kevin Duffy has labelled objections to the proposal as 'all a political stunt' by groups including the Greens party, the Environmentally Concerned Citizens of Orange and Futuring Orange.

"It is time to take a stand in this instance against the Greens and get urgent approval for this site," he said.

Cr Duffy said thousands of Orange schoolchildren were missing out on having quality sporting facilities.

He said he was concerned findings by the Heritage Council, including calling for a development control masterplan for the site, would lead to extensive delays, and even the loss of the state government's $25 million funding for the project.

ECCO and Futuring Orange have written to Premier Gladys Berejiklian and Planning Minister Rob Stokes asking them to intervene in the issue which would see 513 trees removed.

"It would be most helpful if Orange City Council could be assured that the deadline for project completion can be relaxed or extended," the letter stated.

They said there were concerns the trees might be chopped down before planning approval was granted for the sports complex.

However, Cr Duffy said it was time for action.

"Council has followed due process from day one with this approval," he said.

"Minister Don Harwin (Special Minister of State) and minister Melinda Pavey (Water, Property and Housing) need to urgently visit Orange and the site with the NSW heritage approval committee so council can get on with the job of building the much-needed sports complex.

"There are approximately 8000 students in the Orange district that would benefit from the first project that is intended, the athletics precinct."

Many of the trees to be removed from the former Country Club golf course site would be radiata pines.

Cr Duffy said 50 years ago the site was bare of any trees.

"The most considered green council in NSW is the Blue Mountains council. They have radiata pines as noxious," he said.

Cr Duffy said the green groups wanted council to build the sporting complex at the first site proposed, near the Northern Distributor Road.

He said that site had more than 200 native trees on it, which would likely have to be removed.

"Sports clubs need urgently to speak up and let us not lose this $25 million," he said.

"If these ministers bow to the 'greens' pressure it will become obvious that the government never intended to honour the $25 million project."

Opponents to the Bloomfield site as a sporting complex have said it would be better suited to becoming an urban park. However, Cr Duffy said since the golf course had closed few people had visited the area. "I go there at least 8-10 times a day and there is no one out there," he said.

Cr Duffy said the Heritage Council had delayed other projects in Orange including the Orange Hospital and he was concerned it would happen again.

An extraordinary council meeting was planned for April 27 to decide the fate of the trees. However following the Heritage Council's findings that is now likely to be delayed.
