Carll, go south to the rocks just past the Karadene hotel from the river mouth (blind most times) for your best bet. I used to fly and lure fish there regularly. On a good day I have caught 20 + shad on fly, I've also caught 5 species on a morning session, shad, kingies, pompano, wrass and river snapper.
The stretch from the Illovo river including the river itself south to the Karadene hotel can also produce on the right tide. The Illovo river used to have kingies, river snapper and bream.
One word of warning, watch out for the banditos, don't fish alone if you fishing the rocks to the south.
