The
New South Wales Labor Party previously proposed a similar policy in November 2018 and took it to the
2019 state election. The national park would have been located within a sliver of bushland named Smiths Creek Reserve in
Campbelltown. The party was unsuccessful in implementing the policy as they were not elected to government. During the
2023 state election campaign, the Labor Party proposed a national park to be located between
Glenfield and
Appin. They were successful in gaining government under leader
Chris Minns so planning commenced. The government is investing $48.2 million to implement the policy which includes additional measures such as a koala care centre, support for volunteers and investments in protective infrastructure. The state member of parliament for
Campbelltown,
Greg Warren, has been an advocate for the proposal. Action was taken to implement the policy through the Cumberland Plain Conservation Plan in 2023 alongside urban developments, which will eventually enable up to 73,000 new houses. ==Name==
