The Berejiklian government's response to a confidential audit of new native vegetation laws that found a 13-fold jump in land clearing, and its refusal to consider appointing an independent umpire to preserve key wildlife, has been condemned as "totally inadequate".

A week after Agriculture Minister Adam Marshall released the highly critical secret review of the new laws by the Natural Resources Commission - that ministers had sat on for eight months - the government issued its formal response.

The government "noted" or gave "support in principle" to most of the recommendations, such as backing a "process to allow for the monitoring of unexplained clearing".

It gave no firm commitment to fix codes now in operation for two and a half years despite the commission finding a "statewide risk to biodiversity".

The government instead "noted" or gave "support in principle" to most of the recommendations, such as backing a "process to allow for the monitoring of unexplained clearing". That was despite the commission finding such "unexplained" activity made up as much as 60 per cent of the total.
