Greens MP David Shoebridge delivered a notice of motion to Parliament this week as he intends to introduce a bill proposing to apply statutory protections to the Killalea State Park.

That will ensure the state government adequately funds the maintenance of the area and gives control to a community board.

Current managers, Reflections Holiday Parks, has proposed to build 15 luxury "eco-cabins" and a 200-seat function centre, 53 full-serviced campsites, a new playground, walking trails and outdoor recreational equipment for more than $10 million with the help of a $6.5 million state government grant.

However, the alliance and many community members have repeatedly said they do not want the site to be developed, rather they are campaigning for it to remain untouched to preserve its environmental, social and cultural values.

"I've met with the Save Killalea Alliance on site, I know how beautiful and unspoiled the park is and it is the job of the NSW Parliament to keep it that way," Mr Shoebridge said.

"This bill will protect and conserve Killalea for future generations and ensure it is not developed for private interest and private profit."

Mr Shoebridge said the bill was in its drafting stage and was based on existing protections given to Centennial Park and Parramatta Park which preserve the unique character of the large green open spaces from development and have a community trust or board that acts as custodian of the land.

He said he wants to continue to work with alliance members, the community and Shellharbour MP Anna Watson on the bill and hopes to have a draft detailed consultation out in a "number of weeks".

Mr Shoebridge said the state government had a responsibility to fund the park's maintenance rather than make it "pay its own way" through generating revenue via commercial ventures.

"The problem with the Reflections model is they want Killalea to be a revenue-raising facility and that is a very short road to the destruction of the green open space," he said.

Alliance convener Peter Moran said members welcomed the support and action from Mr Shoebridge, as well as Shellharbour MP Anna Watson, who have taken different strategies to achieving the protection of the well-loved reserve.

"The alliance welcomes the good faith involvement of both of them," Mr Moran said. "We are happy to work with them to gain a level of protection for the park.

"We have heard Ms Watson is quite confident of a favourable outcome relating to the transfer of Killalea from Crown land to the National Parks and Wildlife Service but there has been no firm commitment from the government at this stage.

"The Alliance's position is to see the park transferred to the National Parks and Wildlife Service but we are open to Mr Shoebridge's proposal because even national parks can have some level of development occur in them or a gate fee; and it would not necessarily receive the level of funding required to ensure its sustainability into the future.

"What Mr Shoebridge proposes, through the bill, are statutory protections that will mean Killalea becomes a standalone park.

"We as community members pay our taxes and therefore part of taxes should be used to provide open green space.

"The Alliance hopes and expects the government will then provide funding to protect environmental assets.

"The Save Killalea Alliance will continue down all avenues to have the reserve protected."
