Green Patch is one of Booderee National Park's most popular beaches and campgrounds, a calm, sheltered stretch of sand on the southern shore of Jervis Bay. Parks Australia describes it as very safe, with calm water suitable for families and people learning water skills, and notes that visitors can see octopus, squid and fish around the rock platforms. The Shoalhaven tourism body also lists it as a good spot for learners.

The rock platforms at each end of the beach carry weed and small ledges where octopus hide, and squid hover over the sand and seagrass, especially during their seasonal egg-laying. Blue groper, luderick, leatherjackets and schools of small fish are common, and rays cross the sand. The park's wildlife is part of the experience – wallabies, lorikeets, parrots and echidnas frequent the grassed areas.

It is primarily a snorkelling and swimming venue with good facilities: picnic areas, gas barbecues and a campground. For scuba, Murrays Beach nearby is the better choice, but Green Patch makes an easy first snorkel or a relaxed shallow dive. The beaches are unsupervised, animals must not be fed, and a Booderee vehicle pass is required. Scottish Rocks, a ten-minute walk away past Bristol Point, offers the park's best snorkelling. Campers can snorkel morning and evening when the water is calmest, and the shallow, sandy bottom makes it a forgiving first snorkel for children. Water temperatures range from about 15 °C in late winter to 23 °C in late summer, so a 5–7 mm wetsuit is sensible for anything longer than a quick summer snorkel, and a hood helps from June to October.

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 (vehicle pass required) and follow the signs from Jervis Bay Road to Green Patch day-use area and campground. A walkway leads from the car park to the beach.

Snorkel along the rock platforms at either end of the beach; Bristol Point and Scottish Rocks are about 10 minutes' walk east.

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. Green Patch faces north into the bay and is described by Parks Australia as very safe with calm water, though it is unpatrolled and becomes choppy in strong north-easterlies.

Enter from the beach and snorkel along the rock platform at either end, looking for octopus, squid and fish, then cruise back over the sand.

No operator; a family snorkelling and camping area.
