Magic Lands on Phillip Island's south coast is a stretch of reef and bommies sitting in around 14 m of Bass Strait water, named for the rich underwater landscape of sponge gardens, kelp canopy and granite outcrops. Marine life is excellent — crayfish, abalone, weedy seadragons, blue devils, schools of sweep and bullseye, plus the occasional fur seal cruising through. Boat access only, run from Newhaven or Cowes. Like every site on the island's south coast it's exposed to swell from south through south-west, so flat-day windows are worth grabbing when they come. Best in light north-east winds, swell under a metre and tide near slack. Use the live 7-day wind and swell forecast on this page to spot the right day. Intermediate to advanced — open coast, current on tide change, plan a back-up site if the swell is rising on the forecast.
How far you can see underwater — measured in metres. 10m+ is great, 5–10m is workable, under 3m is murk. Driven by wind, swell, and recent rain.
Long-period waves rolling in from the open ocean. Direction matters more than height — a S swell hits Portsea hard, but an E swell rolls past. Period over 12 s = real ocean punch.
Offshore (N or NE) flattens the surface and clears the water. Onshore (SE through SW) chops it up and stirs sand. Calm or light offshore is the magic combo.
This site faces the open ocean. The exposure caption above shows which directions slam in. Anything from the opposite side gets blocked — that's the safest window.
Slack water — the 30 minutes either side of high or low — is calmest and clearest. Mid-tide brings the most flow. Plan to be down at slack, up before the run picks up.
Bass Strait sits 14–16 °C autumn–winter, 17–19 °C summer. Below 16° a 7 mm hooded keeps you warm for 60 min+. Drysuit if you're going long.
