When does the Margaret River sandbar open?

The bar usually breaks with sustained winter rainfall — typically June or July through to spring — and closes again as summer flow drops. The mouth fishery for mulloway and tailor is most consistent when the bar is open and the tidal exchange is running. Check the state of the bar before committing; the lower river above a closed bar still fishes well for black bream.

Can I catch black bream in Margaret River?

Yes — the lower brackish river above the bar holds bream year-round, with the better sessions on small soft plastics, hardbody minnows or prawn baits worked along snags and rocky banks at dawn and dusk. Late summer and autumn before the bar opens are the prime months. The river fishes catch-and-release-friendly; bream stocks here aren't large.

Is fishing safe at Surfers Point?

The rock platforms at Surfers Point and Riverlea are honest exposed-coast ledges — fishable in moderate swell with grippy footwear, dangerous in heavy swell. The wider Margaret River region has a known white shark population and a history of incidents. Check Sharksmart and the swell forecast before each session, never fish low ledges in big seas, and never alone after dark.

How long is the drive from Perth?

Around 3.5 hours via the Forrest Highway, Bussell Highway and Caves Road into Prevelly. Multi-day trips are the norm; combining Margaret River Mouth with Gracetown to the north and Hamelin Bay or Augusta to the south covers the south-west coast's main land-based fisheries in a single weekend.
