Best tide state to fish Derby (Derby Jetty / King Sound)

The eleven-metre tides dominate everything — the water rips through King Sound, and slack water around the neaps is the productive window for lure fishing. The dry season, May to September, is the comfortable visiting window with settled weather and clearer water. The wet, November to April, brings the barramundi run-off but also cyclones, heat, flooding and stinger risk, and many operators stand down. Water is turbid through most of the sound, so this is a tide-and-structure fishery, not a sight fishery.

What anglers target here

Anglers fishing Derby (Derby Jetty / King Sound) typically time sessions around the tide for barramundi, king threadfin salmon, mangrove jack, queenfish, and giant trevally.
