The serious reef fishing on the Sunny Coast is a long way offshore. Personally I feel anything that is small enough to be really versatile as far as creek and estuary work is concerned will be a bit small for the bluewater if you are wanting to fish areas like the Barwon's and the Hard's. I went through the same thing myself when upgrading to a 6 metre rig from a 4.5. Ultimately ended up with a cheap tinny for the creeks as well.
