We have travelled through South Australia several times on our way from Victoria after fruit picking to The Harts Ranges in the Northern Territory to do some fossicking, but have not done much fishing there.
However we have got a good feed of sand crabs also called blue swimmers on one trip when we stayed a while at Port Germein for a visit. South Australia is famous for crabs and they are easily caught in dilly’s off the Port Germein jetty, but prepare yourself for a long walk. The Port Germein jetty is the longest in South Australia and, reputedly, the longest in the southern hemisphere and the best crabbing is at the end.
The western side of the state is another area we have fished and managed to get a feed of Tommy Rough and the odd King George whiting.
We only beach fished here and I believe to get the big King George whiting a boat would be very handy. South Australia is also famous for Squid and these can be taken off the jettys all over the state.
