The NSW government has committed to only 11 of the 42 recommendations made by a parliamentary inquiry into koala protections conducted in the aftermath of the 'black summer' fires.
The NSW government response, released on Wednesday, also supported 17 of the recommendations in principle.
The remaining 14 were "noted".
Nearly three billion animals - including 60,000 koalas - are estimated to have been killed or injured during the 2019-20 horror bushfire season.
Greens MP and Committee Chair Cate Faehrmann said the response was extremely disappointing and showed the government's lack of commitment to saving the koalas.
"Of the 42 recommendations in the report, 14 were 'noted' which from where I'm sitting is another way of saying 'rejected'," she said in a statement.
"This is especially disappointing because they are all achievable if the government had the will."
Among the recommendations left on the table was that a Great Koala National Park be set up, and a plea for more funding for forestry regulator the Environmental Protection Agency.
Significantly, the government also declined to support the recommendation it investigate applying core koala habitat protection requirements to private land, to replenish habitat lost in the bushfires.
"The NSW Biodiversity Conservation Trust will continue to work with landholders to encourage koala habitat conservation on private land," the response read.
The issue has been a vexed one for the government.
In September, NSW Nationals leader and Deputy Premier John Barilaro threatened to blow up the coalition government if concessions weren't made to rural property owners for protection measures relating to core koala habitat.
The Liberals and Nationals appeared to have reached agreement on policy in October, but the government was forced back to the drawing board after one of its own MPs voted against the compromise.
The amendment's failure to pass parliament forced the government to revert back to operations under the former environmental planning policies, while a new policy is developed.
The government did however agree to rule out opening up old growth forests in the state forest reserve for logging and to work with Indigenous fire practitioners to document the benefits of cultural burning.
It also supported in principle prioritising the protection of koala habitat during future bushfires, and that climate change mitigation be factored in to the drafting of koala protection legislation and planning strategies.
