The beaches around Rompin have small threadfin and heaps of catfish, thats about all i know of beach wise. On really light spinning / popping gear - the long toms are good sport (did i really type that in a GT forum?).
As everyone has mentioned, Rompin and the sails, when they are on the chew - lures raise them brilliantly. The fishing is great - boats leave a bit to be desired. The fishing can be SOOOOO good it compensates for it.
Feshwater fishing? I've caught a heap of haruan around Rompin on small topwater and diving lures.
