Australia

In Australia, the 1992 National Forest Policy Statement made specific provision for the protection of old growth forests. The NFPS initiated a process for undertaking assessments of forests for conservation values, including old growth values. A working group of state and Australian Government agencies took the NFPS definition into consideration in developing a definition that was accepted by all governments.
In 2008, only a relatively small area of Australia's forests had been assessed for old-growth values.
Of the of forest in Australia assessed for their old-growth status, is classified as old-growth. Almost half of Australia's identified old-growth forest is in NSW, mostly on public land. More than 73% of Australia's identified old-growth forests are in formal or informal nature conservation reserves.
In 2001, Western Australia became the first state in Australia to cease logging in old-growth forests.
