Shellharbour City Council is partnering with the park's management for the free guided walk with nature expert Carl Glaister and park manager Nathan Cattell.

The park is home to threatened plant species, remnants of subtropical rainforest, littoral rainforest, wetlands and a freshwater coastal lagoon that provides a breeding habitat for birds, frogs and aquatic creatures.

Participants can keep an eye out for white-bellied sea eagles, lizards and echidnas.

The discovery walk, to be held on Saturday, August 23, will incorporate Mystics Beach and the back of Minnamurra and will run from 9.30am to 12.30pm.

Priority for this free walk will be given to Shellharbour residents.

Children aged over 10 years are welcome to attend if accompanied by an adult.

After the walk, participants can enjoy a free barbecue lunch.

Bookings are essential and can be made by contacting Shellharbour Council on 4221 6111 or sustainability @shellharbour.nsw.gov.au.

Meantime, the wait continues for the release of Killalea State Park's revised plan of management.

A world-class surfing facility, a walking track that links Bass Point to Minnamurra and a new road that diverts traffic away from Shell Cove will be among the projects up for discussion when the draft goes on public exhibition.

Mr Cattell said the Killalea State Park Trust was still working through the draft plan.

"The draft will be the subject of extensive community consultation, including the council, neighbours and community groups, but there is no time frame at the moment.

"We are hoping to get the draft on exhibition as soon as possible, but there are no confirmed dates," Mr Cattell said.
