About Jenna's Bump
Jenna's Bump was described in Spirit Divers' Batemans Bay site guide as a relatively new site the shop had started diving. It was rated Easy for Open Water divers, with a maximum depth of 18 m and suitable for day and night dives. The description is short: lots to see, including wobbegongs, octopus, nudibranchs and sea dragons.
The name suggests a small rise or bommie on the sea floor, and such features in Batemans Bay typically consist of low rock with kelp, weed and sponges surrounded by sand. They attract resident animals because they are the only structure in an otherwise sandy area. Wobbegongs rest under ledges, octopus make dens in the rock, nudibranchs feed on the sponges and hydroids, and weedy sea dragons drift over the weed. Blue groper, leatherjackets, sweep and red morwong are also likely.
No position has been published, and it is not clear whether the site is still dived under this name. If you want a similar dive with better documentation, consider Tiger Reef or Occy Point at the Tollgate Islands, which have the same mix of sea dragons, octopus and nudibranchs. Divers who know the site are encouraged to record its position and depths, as local operator-named sites tend to disappear from the record when shops close or change hands. Any update should go to the local operators and regional directories, together with a position, depth range and short description.
Getting there & entry
Relatively new boat-dive reef near Batemans Bay with wobbegongs, octopus, nudibranchs and sea dragons; to 18 m.
Boat access only. The site was named and dived by Spirit Divers from Batemans Bay; no position has been published. Launch at Hanging Rock ramp and obtain the mark from a local operator.
Like most bay sites it is likely to be within 10–15 minutes of the ramp. Private boats should confirm the location before leaving, as there is no public mark.
Entry: Giant stride from anchored boat
Facilities: Hanging Rock boat ramp; air fills at Beneath the Bay.
Weather, swell & tides
Sites inside Batemans Bay get shelter from southerly swell from the southern headlands and islands, so they are diveable on many days. Strong easterly swell wraps into the bay and causes surge, and strong westerly winds make the anchorage choppy. After heavy rain the Clyde River floods the bay with brown water and visibility can fall to a few metres for days.
Best season: Year round
How the dive is usually run
Descend onto the bump, circle it slowly at 12–18 m searching the ledges for wobbegongs and octopus, then move up onto the top to look for sea dragons in the weed. Return to the anchor line with gas to spare and ascend on it.
