Mangles Bay is the sheltered water between Point Peron and Garden Island — a protected, north-facing bay that's been Perth's most famous snapper spot for generations. Seagrass meadows, sand patches, and easy wade access make it a genuine multi-species fishery: whiting and flathead on the flats in summer, bream around the edges, squid over the weed, and a legal window for snapper either side of the spawning closure.

Wade the sand patches between seagrass at first light for yellowfin whiting and flathead — small surface lures or lightly weighted prawn baits on light gear. King George whiting sit on the cleaner sand edges; drift baits like squid strip or pipi on a long-shank hook. For snapper (outside the closure), fish the deeper water towards the Garden Island causeway at dawn/dusk with mulies or soft plastics. Squid jigs work over the weed in spring and summer.

King George and sand whiting (summer flats), yellowfin whiting (wading at first light), flathead (sand edges), bream, herring, squid (over seagrass), and pink snapper in the legal window. Blue swimmer crabs are a headline through the Cockburn Sound season.

Pink snapper fishing in Cockburn Sound is closed 1 October – 31 January to protect the spawning aggregation — no targeting, no retention, nothing. Check DPIRD before you go. The bay is shallow and seagrass-heavy, so light gear and clean presentations beat heavy tackle. It's also a busy recreation zone — boats, kayaks, swimmers — so keep casts controlled and fish the quiet margins at dawn and dusk.
