Mandurah sits at the mouth of the Peel-Harvey Estuary — one of WA's most productive fisheries. The foreshore channels funnel bait on the tide, and the estuary mouth is a highway for fish moving between the system and the ocean. It's also blue swimmer crab country from November through April.

Fish the edges where tidal current funnels through the channels. Herring and tailor stack up along the flow lines, especially on the change. For bream, work the pylons and structure with bait or soft plastics. At night, squid jigs do well along the lit sections of the foreshore.

Herring, bream (strong estuary population), tailor, squid, blue swimmer crabs (Nov–Apr, check DPIRD for closures), and mulloway in the deeper channels.

The foreshore gets busy with walkers and families — keep casts controlled and be aware of people behind you. If you're after crabs, bring a net and a measure — compliance officers are active here. The estuary system is massive, so if one spot is quiet, move.
