What is the Plug at Bunbury?

The Plug is the local name for the breakwater and bridge structure at the southern end of Koombana Bay where the channel links the bay to Leschenault Inlet, with gates that can be closed during big storm surges. It has a long-running reputation as a squid hotspot, with the Casuarina breakwater walls and the inner harbour rocks the productive land-based sections.

Can I catch squid at Koombana Bay?

Yes — the Plug breakwater and the Casuarina Boat Harbour rock walls are both productive squid spots year-round, peaking through spring and again in late summer to autumn. Fish 2.5–3.0 jigs in pink, orange or natural patterns slowly along the rocks and over weed patches, and head out around dusk into dark when the lights pull bait.

Is Koombana Bay good for kids?

Yes — sheltered water, sealed access, public toilets, cafes and a tackle shop within five minutes, plus a productive but light-tackle fishery for herring, skippy, KGW and squid. The Dolphin Discovery Centre is right on the bay too. It is one of the better family fishing destinations in the South West.

How does Koombana compare to Bunbury Back Beach?

Koombana is the sheltered counterpart to Back Beach. Where Back Beach is exposed surf with gutters and a tailor and mulloway focus, Koombana is calm-water structure fishing with a squid, KGW and bread-and-butter focus. Pick Koombana when the open coast is blown out, or for a session with kids. Pick Back Beach for the autumn salmon run and the nighttime jewfish shot.
