Secret Harbour has deep channels and gutters carved by the reef system offshore. The name doesn't help keep it quiet — it's well known among Rockingham-area anglers — but the beach is long enough that you can find space. Larger tailor show up here toward the end of summer, and the deeper features hold mulloway in spring.

Walk the beach looking for channels where water drains between reef sections — these funnels concentrate bait and fish follow. Cast metals through the channels at dawn and dusk for tailor. For mulloway, fish the deeper channels at night with fresh bait on the bottom. The outgoing tide draining through the channels can be the most productive window.

Tailor (late summer produces bigger fish), mulloway (Nov peak in channels), herring, whiting, and Australian salmon when the autumn run hits.

The reef sections can snag you up quickly — bring spare rigs and don't use your best lures over the rocky bottom. Fish the sandy channels between reef patches rather than casting directly over the reef. The larger tailor here tend to show up Feb–Mar when the smaller fish have moved on.
