"We're looking forward to negotiating a memorandum of understanding with the CaPTA Group and planning the next steps forward which include, firstly, considering the needs of the community and identifying an appropriate site," Gunnedah mayor Jamie Chaffey said.
"Importantly, the facility would also include a koala hospital to help battle the many threats faced by our koala population."
The council's director corporate and community services Colin Formann said "attracting a company of the calibre of the CaPTA Group is a real win for Gunnedah".
The koala park project was awarded $6.48 million in June 2018 through the state government's Regional Social Benefit Infrastructure Fund.
Cr Chaffey said this "milestone" gave him confidence of future progression with a "quality operator that is well established and has much to offer".
"The park will be a wonderful addition to the shire, both in terms of tourism, the economy and in helping protect the iconic animal that has become synonymous with Gunnedah. This park ensures we keep our title as the Koala Capital of the World."
