A mate of mine has been cleaning up on yellowfin whiting early in the mornings out at that point in the pic I've provided. That's the bent st boat ramp on the right hand side. Just around the corner from shoalwater.

 Seen as beau and myself live down in that area we can try and give you some advice:

First up,six days will most likely put you down here around Easter time,so where ever you go with your three year old(ie jetty's in the Rockingham area) they are going to be very busy and good luck getting a reasonable spot on the jetties.

Palm Beach jetty would most likely be the most "child friendly" jetty with it's lower jetty structure.

Kwinana Beach jetty is closed and has not been repaired from the storms over the winter period.

Val Street jetty is okay,but too many kids are swimming/bombies off it,while you are trying to catch some fish.

As for beach fishing,pick the wind direction,(ie eastly wind or seabreeze) and fish either the Safety Bay side or drive around to the Mangles Bay/Rockingham Beach side,you should get some whiting or herring off the beach if you berly up.

 fishing with your son try early mornings or late arvos along the beach in shoalwater! you can target herring and gardies using a float with the burly hole in the centre and a small hook size six or eight! or you can use a standard paternoster rig for whiting flounder and flat head! the sand bar across to penguin island is very good for flat head but watch the cross currents! if you travel further south down to warnbro beach late arvos can bring all those fish plus tailor! for the tailor i like to use a small gang and bluebait! when fishing dont go for the furthest cast away from the beach you will be surprised how close the fish are to the shore! point peron is great for herring at the moment just watch the swells and it is a rocky area so not the best place for the young fella! if you can get out to pengin island there is great fishing all around the island! plus you can show the boy the penguins! long point boat ramp is also good for all the fish mentioned above plus a few squid! if all else fails take him to the bent street boat ramp he will have a ball with the trumpeters!! good luck

 i do love the exclamation mark!!! 

thanks fellas -really appreciate your sound knowledge and advice. definately gonna try the jetty near fisher street as long as its not mobbed out!! Beau how difficult is it to get along to the sandy spot on the point?? will a 2 wheel drive vehicle get there or better off walking??  Snappermiles any recommendations for burley?? or just the usual stuff  i generally use the mako burley and oil and mix a couple tins of snappy tom with it  do u suggest anything better

cheers :)
