Environment groups who walked away from law reform talks with the NSW government have called the consultations a complete failure.
"We have sat in a room for almost a year. We're sick of wasting our breath," said Total Environment Centre chief executive Jeff Angel.
All six of the conservation groups involved in the talks have withdrawn, slamming the proposed laws for threatening clean water supply and already endangered species, and also accusing the Baird government of prioritising development over the environment.
The group predicts the replacement laws will go to cabinet this month.
"That will be the start of a very big battle between us and the government and their war on trees," said Mr Angel.

National Parks Association chief executive Kevin Evans said removing existing natural vegetation protection would leave native animals vulnerable to extinction.
"Over 1000 native species are already threatened with extinction. We're already calling the extinction of koalas by 2025," he said.
The other four groups are the Wilderness Society, WWF Australia, NSW Nature Conservation Council and the Humane Society.
