The bluespotted flathead is the common flathead of Sydney Harbour, Botany Bay and the coastal shallows, named for the vivid blue spots on its fins. Easy to catch and superb eating, it is a favourite target for a relaxed day drifting the sand flats.
Bluespotted flathead are a smaller, more numerous cousin of the dusky, easily told apart by the bright blue spots on their tail and fins. They live over the sand flats, estuary channels and coastal shallows in and around Sydney, lying camouflaged on the bottom and ambushing prawns and baitfish as they drift past.
They are one of the easiest fish to target on the harbour, which makes them perfect for a fun, productive session, and they bite freely on both bait and lures. What they lack in size they make up for on the plate, with clean, mild, white flaky flesh that is excellent eating.

Bluespotted flathead are an easy, obliging target, ideal for a fun light-tackle day on the harbour.
Drift the sand flats and channel edges and work a soft plastic or a lightly weighted bait, prawn, pilchard or squid strip, along the bottom. Like all flathead they ambush from the sand, so the bite usually comes on the drop or the pause. Keep drifting to cover ground until you find a patch of fish, then keep working it. Blades and small plastics hopped back to the boat are deadly, and everyone from first-timers to seasoned anglers can get among them. All the gear is on board and ready to go.
Getting among the flatties is about reading the flats and setting a drift that covers the productive sand on the right tide. George Aslanian has spent more than 30 years fishing Sydney Harbour and Botany Bay and knows where the fish stack up. On a light-tackle harbour session we set the drift, rig you with plastics or bait, and keep you covering ground so the whole crew stays busy. Keen to get among them?
