Earlier this year I flew coastal from Ballina to Wollongong. Absolutely stunning scenery, would highly recommend it.
Willy; I rang a few days earlier to discuss the coastal transit, RAAF were very happy to discuss. I also rang before i launched at TRE to ensure it was still good, had a plan in the system. Called at Sugarloaf point, and only had 2 orbits at Anna Bay. Buzzing down the beach at 500ft was incredible and spectacular.
Victor 1 was equally spectacular. Tried for the Sydney scenic but didn't get a clearance despite calling at Barrenjoey. Regardless, keep a good lookout near the heads (Had a floatplane pass me opposite direction pretty close) and ensure you don't stray into CTA.
