The track from Pearl Point to Conran (via Dock Inlet and Yeerung)is now management only but you can come across via the Old Coast Rd. The track to the Yeerung Gorge turns off it and is worth a look. Up in Croagingolong Thurra River is worth a look, big dune, lighthouse(they do tours but not sure on timing) and Meuller Inlet (used to be canoes for hire but have not been there for a bit so not sure!). Wingan has a broad walk down to the beach (a couple of km walk) that looks out to the Skerries (seal colony) and walks into Elusive Lake and the rapids/rainforest.
Will need to check if you plan on camping as most places book out this time of year.
Have fun!
