Here is the Round 6 Adelaide Estuary Boundary information. The outer boundary is basically a line from Chads Creek to the tip of the last bay before Shoal Bay. The upstream boundary is Castle Creek as per previous years.
It is a big area with quite a few hazards. Please be careful when moving about the various systems.
Hopefully the road to Leaders and Saltwater Arm will remain in reasonable condition over the next few weeks. I guess there is always the trip downstream from the Adelaide River bridge as an option.
