For your mountainbike adventures on your way back down the coast make sure you stop at Glenrock in Newcastle, Awaba on the western side of lake Macquarie, Ourimbah on the Central Coast, Taree,, Port Macquarie, Kempsey, behind the golf club on the southern side of town and Mt Annan in the south west of Sydney. Probably wont have time to ride them all but if you rode Glenrock, Awaba, Ourimbah and Taree you would probably get the best of them.
