Mangles Bay, Cockburn Sound — the most consistent winter KG mark in metro Perth. Sandy bottom near patchy seagrass beds in protected water. Wade out to the sandy patches and cast into the gutters. Mid-morning on a rising tide on a flat day is the standard winter window. Fresh pipis or tube worms on a small long-shank hook, light line, patience.
Palm Beach Jetty, Rockingham — the standout winter jetty for both KGs and yellowfin whiting. The water is shallow over sand and weed, the jetty structure pulls fish in, and unlike a lot of metro jetties, it actually fishes through winter rather than going to sleep. KGs cruise close to the pylons on a rising tide.
Rockingham Jetty — the sheltered Cockburn Sound stand-in now the jetty at Woodman Point is out of action. That jetty, listed in some spots as Ammo Jetty and in others as Woodman Point Jetty, is the one structure, and it’s closed from mid-2026 until around 2027 for a rebuild. Rockingham fishes the same way — KGs, herring, the odd late squid before the new season starts in August, and whiting through winter that most anglers underrate. Fish the deeper end on the change of tide.
Rottnest Island — if you’re prepared to take the ferry and the bike, the north-side bays around Rotto sit in the lee of the prevailing winter southerly and fish for KGs when the metro shore is wind-blasted. Geordie Bay, Longreach Bay and the inner east coast around Thomson Bay all hold fish on a calm day. The bonus: you’ll usually have the spot to yourself in June.
Point Walter, Swan River and Applecross Jetty — the Swan River runs cooler in winter and the whiting bite slows compared to summer, but yellowfin and school whiting still come through on the sandy flats inside the river. Worth a quiet session on a still afternoon when the metro coast is unworkable. River winter whiting fishing is more about the walk than the haul, in honesty.
