Hard bodies: AC invaders, Oar-gee Plows, Custom Crafted Hammerheads and extractors, stumpjumpers, jackalls and anything else large with a slow action. I'm sure the tackle shops down there will put you onto something good
Soft Plastics: Never used them personally, but the squidgee slick rigs look great, especially in the redfin colour

.
Spinnerbaits: Anything big and flashy. Not sure on the colour or blade colour for the murray, but here in the bidgee i prefer gold and nikel. Use the colorado blades (spoony looking blades) in water around about 3m deep. Any deeper or for fast water i use the willow leaf blades as they sink faster. My favourites are Mudguts and also the Compleat Anglers home brand "angler tech" spinnerbaits.
Best of luck
