Any tips for fishing spots/ fish to target on a weeks hols down Margaret River?

 Hi guys just off down to Prevelly/ Margaret river for a week this sat, been there a few times and had a bit of luck at Eagle bay with Bream an other stuff but not much else, havent had the chance to fish canal rocks yet but it looks fishy to me. Anyone know of any areas round that or the Margaret river area that would be worth a go? Its nothing but herring round these parts for me at the mo so a change would be good, all ideas welcome, cheers!
