Jibbon Beach is a sheltered, north-facing beach at the eastern end of Bundeena, where the village meets Royal National Park on the southern side of the Port Hacking entrance. It is best known as a snorkelling spot, with clear water, a sandy bottom, seagrass and rocky reef running out towards Jibbon Head, and it is also a pleasant, easy shore dive for trainees and those who want a relaxed look at estuary-mouth life. The main feature to be aware of is a sudden drop-off in the seabed, which takes swimmers from shallow sand into deeper water quickly.

Local tourism sources describe groupers (eastern blue gropers), cuttlefish and a variety of fish; from the wider Port Hacking area divers can expect luderick, bream, yellowtail, leatherjackets, stingarees, flathead on the sand and occasional weedy sea dragons on the reef margins. The beach is backed by bush and forms the start of the Jibbon headland loop track, which leads to an important Aboriginal rock engraving site on the headland – a reminder that this is Dharawal country with a long history of use. The site's shelter comes from Jibbon Head and Jibbon Bombora, which block southerly swell, but it is open to north-easterly chop.

Access is by road through the national park or via the Cronulla–Bundeena ferry, which makes it a good non-boat option on the southern side of Port Hacking. Documentation for scuba diving here is limited; the details above come mainly from snorkelling guides, so treat depths as indicative. It suits snorkellers, beginners and families, and divers looking for a quiet shallow dive.

Drive through Royal National Park to Bundeena (or take the Cronulla–Bundeena ferry and walk) and head to the eastern end of town; Jibbon Beach is reached from the end of Beachcomber Avenue / Bonnie Vale area and the start of the Jibbon headland loop track. Street parking is limited and fills on summer weekends. Walk down to the beach with gear; entries are from the sand at either end, with the rocky reef towards Jibbon Head at the eastern end.

The ferry option means carrying gear from the wharf – about 1 km.

Jibbon Beach faces north into the Port Hacking entrance and is sheltered from southerly swell by Jibbon Head and the bombora, making it one of the calmer spots in the area. North-easterly winds and swell push chop into the beach, and big easterly seas wrap in around the head. Visibility is best on an incoming tide with clean ocean water; after heavy rain Port Hacking runoff reduces it.

Watch for boats and ferries in the channel beyond the swimming area.

Enter from the eastern end of the beach and follow the rocky reef edge towards Jibbon Head at 3–6 m, watching for the sudden drop-off, then return over the sand and seagrass. Stay inside the bay and out of the channel.

No regular dive operator – a popular snorkelling spot; occasional club shore dives. Air fills at Pro Dive Cronulla (across the river).
