Diving at Burns Rocks / Seal Canyons (Australia)
In the northern reaches of Marmion Marine Park, Burns Rocks (Seal Canyons) is a shallow boat dive of canyons, swim-throughs, caves and walls dropping to about 10 m / 33 ft. The headline is the sea lions, often playing in the surf, sometimes curious enough to buzz you. They've got serious teeth though, so hands to yourself. Rated intermediate.
As evening covers Burns Rocks / Seal Canyons, the local air temperature is measured at 19°C. The current wave height at the surface is recorded at 1.2 m. These late-day readings characterize the surface conditions for the night.
Dive Site Location & Key Facts
Dive Site Overview
The rock here is too big to lap in a single dive, and trying earns you a long surface swim, so this is a site you explore in sections instead of circling. East-to-west canyons cut through it, lined with hard corals and capped at their ends by brain corals, and swim-throughs, caves and walls fill in the rest, all in about 10 m / 33 ft.
The shallow depth is deceptive, because there's a lot packed in: you thread the canyons, duck through the swim-throughs, and keep one eye up for the sea lions that work the surf above. If one comes to investigate, it's a genuine highlight, but those teeth are no joke and the animals are protected, so you keep your distance and your fingers to yourself. Anchor according to the wind, ideally an easterly so you can dive the sheltered south-western side, and save it for a low-swell day. Plan your route before you drop, since you can't lap the rock and you want to finish near the boat. The canyons pack a surprising amount of vertical interest into such a shallow dive.

Best Time to Dive
Summer, roughly January through March, gives you the best scores and the calmest shot at the canyons. Water sits cool to mild, peaking near 24°C / 75°F and falling to about 17°C / 63°F in winter, so dress accordingly. Swell is the deciding factor, climbing from around 1.6 m / 5 ft in summer toward 2.8 m / 9 ft in winter, and a low-swell day is what makes the shallow canyons and surf-zone sea lions safe and enjoyable. The wind direction matters as much as its strength, since an easterly lets you tuck into the protected side of the rock, so check both before you go. Match your anchoring to the wind and keep the swell low, and the surf-zone sea lions become the highlight instead of a hazard.

Dive Experience & Conditions
Expect a shallow but busy dive. You move through canyons that run east to west, weave the swim-throughs, and explore caves and walls, all within about 10 m / 33 ft, so depth never limits you, time does. The sea lions are the wild card. They often play in the surf overhead and may come down for a curious look, and that interaction is the moment people come for. Stay still, let them lead, and never reach for them, because they bite and they're legally protected. Don't try to circle the whole rock; pick a section and work it. Anchor for an easterly wind to dive the sheltered south-west, and keep the swell low so the surf zone stays manageable.
Dive Difficulty & Safety Guidelines
Two things define safety here, and neither is depth. First, the sea lions: they have a serious set of teeth, so admire them, keep your hands to yourself, and never attempt to touch. They're protected under strict regulations, so check the latest marine park rules before you go to avoid penalties.
Second, the layout: the rock is too large to circle in one dive, so plan a section and stick to it instead of risking a long surface swim. The canyons and caves are an overhead-adjacent environment, so move through them with light and awareness, keeping any penetration within your training. Add a low-swell day and the right anchoring for the wind, and an intermediate diver has a manageable, rewarding dive.

Marine Life at Burns Rocks / Seal Canyons
The sea lions are the draw, recorded here playing in the surf and occasionally interacting with divers, and brain coral is confirmed marking the ends of the canyons. A curious sea lion looping past you is the memory you'll take home, earned by staying calm and keeping your distance.
