Murrays Beach is the best-known shore dive in Jervis Bay and a reliable fallback when the outer coast is too rough to dive. The cove lies inside the southern arm of the bay in Booderee National Park, looking across to Bowen Island, with a boat ramp at one end and the rocky headland of Governor Head to the east. From the car park a 300 m walk along a bush track and white sand leads to a rocky, pebbly shoreline.

From about 5 m the temperate reef begins, with typical bottom depths of 8–12 m. The reef, kelp and boulders shelter wobbegongs, eastern blue groper and Port Jackson sharks, and nudibranchs fill the rocky crevices. Small caves add interest, and the Posidonia seagrass meadows nearby are home to seahorses. Visitor guides report giant smooth rays, eagle rays, stingrays, fiddler rays and huge schools of fish, and the Marine Life Network notes shallow rocky reefs, seagrass and small caves between 2 and 10 m. In winter, divers may hear the songs of migrating humpback whales.

The site is self-guided and unpatrolled. Because the Murrays boat ramp is active, a surface marker buoy or dive flag is mandatory, and divers should stay clear of the ramp approach. High tide gives the least current and best visibility; winter visibility often exceeds 20 m, with summer water around 20–22 °C. Spearfishing is prohibited, and Booderee's park rules protect marine life. Scottish Rocks and Green Patch nearby offer excellent snorkelling for non-divers. It suits Open Water divers comfortable with a walk-in and rocky entry.

Jervis Bay is about 2.5–3 hours south of Sydney via the M1 and Princes Highway, turning onto Jervis Bay Road at Falls Creek. Enter Booderee National Park on Jervis Bay Road (vehicle park pass required, about $13 for two days) and follow the signs to Murrays Beach at the eastern end of the road, 25–30 minutes from Huskisson. From the Murrays Beach car park walk about 300 m along a bush track and white sand to the rocky, pebbly shoreline.

Wear hard-soled boots, wade to chest depth, then put fins on. A popular option is a drift snorkel from the beach to the boat ramp.

Inside Jervis Bay the water is sheltered from ocean swell, but the bay is big enough for wind chop: strong north-easterlies (summer afternoons) make the western and southern shores choppy, and southerly or westerly winds affect the northern shore less. Diving is possible on most days of the year at one shore or another. Visibility is usually 8–15 m, better in winter, and drops after heavy rain when Currambene Creek and Moona Moona Creek flush tannin water into the bay.

Tides are small but high tide gives better visibility at the beach entries. Murrays is highly reliable when the outer coast is too rough, sheltered from southerly swell by the southern headland. Dive at high tide for minimal current and best visibility; strong north-easterlies push chop into the cove.

Descend at about 5 m onto the reef off the rocky shoreline, follow it east towards Governor Head through kelp and small caves at 8–12 m, then return over the Posidonia seagrass looking for seahorses. Alternatively drift from the beach to the boat ramp. Surface only with an SMB or flag deployed.

No regular guided shore dives (self-guided, unpatrolled site); Huskisson operators hire gear and give advice; guided snorkel tours visit Booderee.
