HUNTERS will be allowed to shoot animals in national parks for the first time under a deal offered to the Shooters' Party by the NSW Government.

The Herald understands the deal would modify a private member's bill introduced by a member of the Shooters' Party, Robert Brown, to allow hunting in 13 national parks if the Shooters' Party removed demands for enclosed game reserves or safari parks from its draft legislation.

AS THE O'Farrell government prepares to mark its first 100 days, the Labor opposition has accused it of declaring war on the environment to gain political favour with Shooters Party MPs it needs to help it pass legislation in the upper house.

The Greens have also exposed the state-government sponsored Game Council for distributing learning materials to schools that promote conservation hunting. The materials contain photos of young people holding rifles and slaughtered rabbits, goats, cats and pigs.

The Greens MP David Shoebridge said this was ''a very unwelcome incursion'' into schools.

Labor's environment spokesman, Luke Foley, said the government had used its numbers in the upper house to overturn the former Labor government's regulation protecting the Solitary Islands and Jervis Bay marine parks. In April, the Coalition lifted high-risk fishing bans designed to protect the endangered grey nurse shark.

The government has abolished the Environment Department and approved hunting in state forests.

''Whether it is our marine environment being trashed or open season on endangered species … Mr O'Farrell's first 100 days have been marked by a war on the NSW environment,'' Mr Foley said.

''I think Mr O'Farrell and his Environment Minister are sitting back and permitting the National Party, inside the government, and the Shooters Party, outside the government, to reverse the conservation gains of recent decades.''

The Opposition Leader, John Robertson, will today release a list of the government's first ''100 days of failures''.

Families picnicking in state forests are commonly being disturbed by gunfire because the NSW government has opened the gates to thousands of hunters, the state opposition says.

In less than 110 days, the state government has approved 3832 restricted hunting licences for state forests, opposition environment spokesman Luke Foley says.

"Over this term of government, at this rate, there'll be an extra 5000 hunters in our state forests," Mr Foley said today.

"This is further proof that Mr O'Farrell is allowing fringe parties, the Shooters and Fishers Party and the Reverend Fred Nile to control the agenda of his government," he told reporters in Sydney.

The government decided last month to allow recreational hunting in 142 state forests for 10 years, NSW Labor says.

Mr Foley said people relaxing in parks were being exposed to the sound of gunfire and he had experienced it himself.

Fatal shots fired at six wild brumbies in a NSW state forest appear to be the work of an experienced marksman, police say.

Four stallions and two mares were found shot dead in the Newnes State Forest near Lithgow on Sunday afternoon.

Police are now hunting for those responsible for the illegal culling, which happened in the first week that state forests were reopened to hunters.

Inspector Gerry Cahill, from Lithgow police, said it appeared the horses had been shot in the head by an experienced marksman.

"There was no evidence of [horses] kicking afterwards," he said.

Investigators also believe a high-calibre rifle was used.

Inspector Cahill said police would question people who had been permitted to hunt in the forest at the weekend.
