Gia Batta Patch is a small limestone reef in King George Sound that serves as a workhorse site for Albany's dive community. Marine Life Network describes it as a limestone reef in 10-12 m with sponge formations and small fish, suitable for divers of all levels and a good night dive.

The reef is low-relief, with ledges, holes and undercuts in the limestone that shelter a variety of invertebrates – sponges, ascidians, nudibranchs, feather stars, small crabs and shrimps – and small reef fish such as western blue devils, scalyfin, wrasse, bullseyes and cardinalfish. The surrounding sand and seagrass bring cuttlefish, squid, flathead and Port Jackson sharks, especially at night.

With a maximum depth of about 12 m and no swell exposure, it is a practical choice for training dives, check-outs and night dives when outer sites are unreachable. It will not compete with Breaksea Island or the HMAS Perth for scenery, but it is a reliable, easy dive and a good place to practise buoyancy and photography.

Little is published about the site beyond Marine Life Network's summary and the exact location is not given, so divers should arrange it through South Coast Diving Supplies. The name may also be spelled differently locally.

Albany is 418 km (about 4.5 hours) south-east of Perth via Albany Highway. Charter boats and private boats launch either from the Emu Point boat ramp (Emu Point Drive, 7 km north-east of the CBD, with a large trailer car park, toilets and a fish-cleaning station) or from the town ramp beside the Albany Waterfront marina in Princess Royal Harbour, which exits into King George Sound through the harbour entrance past Possession Point. Gia Batta Patch is a short boat run within King George Sound; the mark is held by the local dive shop and club and is not published.

It is typically dived from a charter or private boat anchored on the sand beside the reef.

King George Sound is sheltered from the Southern Ocean by Flinders Peninsula, Bald Head and Breaksea and Michaelmas Islands, which is why Albany can offer diving on days when the open coast is wild. As an inner-sound patch reef it is protected from ocean swell and mainly affected by wind chop; strong easterlies or westerlies over 20 knots make anchoring uncomfortable. Visibility is moderate (8-15 m) and drops after winter rain.

Anchor on sand beside the patch, descend and circle the reef at 10-12 m, looking under ledges for invertebrates, then return to the anchor line. At night, keep the circuit small and use the anchor line as the reference.

South Coast Diving Supplies (Albany) – the town's dive shop; runs scheduled boat dives in King George Sound most weekends and on demand in summer/autumn, and issues HMAS Perth permits – used for training and night dives.
