The SS Satara is described locally as the east coast's largest wreck dive, a 5,272-ton, roughly 125-metre steamship built in 1901 by Denny Brothers at Dumbarton, Scotland, and operated by the British India Steam Navigation Company on runs between Sydney, Newcastle, Gladstone, Singapore and Calcutta. On 20 August 1910, under Captain Hugill, she struck the Edith Breaker while navigating Seal Rocks' inner channel at quarter past midnight, was fatally holed and sank in just twenty minutes accompanied by a large explosion; of 89 people aboard, remarkably only two died, with two passing steamships, the Orara and the Dorrigo, rescuing the survivors from lifeboats, the last five including the captain recovered by the Dorrigo. The wreck went unlocated for decades before eventually being found and is now protected under the Underwater Cultural Heritage Act 2018.

Today the Satara rests at 38 to 44 metres on a sandy bottom scattered with rock formations, with her bow relatively intact and hiding a number of artefacts, while the sides amidships and aft have largely collapsed, offering limited but real penetration opportunities for suitably trained divers. Given the wreck's genuine scale, a minimum of 30 minutes is needed just to circumnavigate the hull, and the site is considered a technical dive exceeding straightforward recreational limits, with light current typical at depth but noticeably stronger current possible in the upper water column during the ascent and safety stop. As one of the most significant and well-preserved historic wrecks on the NSW coast, both for its scale and its dramatic loss, the Satara draws technically qualified wreck divers specifically to Seal Rocks, and is usually paired on a trip with a look at Big Seal Rock's shallower grey nurse shark gutters given the proximity of the two sites.

Boats for the Seal Rocks sites either run the longer distance down from Forster/Tuncurry (about 45-60 minutes) or launch locally from the small boat ramp at Seal Rocks village itself, near Sugarloaf Point, cutting the run to Big and Little Seal Rock down to 10-20 minutes. Seal Rocks is a small, remote settlement reached via Lakes Way/Mungo Brush Road through Myall Lakes National Park; there is no dedicated dive shop in the village itself, so most Seal Rocks charter diving is booked through Forster Dive Centre, with divers sometimes meeting the boat locally rather than travelling from Forster.

Seal Rocks sits on an exposed headland with Sugarloaf Point taking the full force of easterly and south-easterly swell — trips are cancelled in anything beyond about 1.5 m swell, and the site is often diveable when more sheltered locations further north are blown out, or vice versa, so conditions should always be checked specifically for Seal Rocks rather than assumed from Forster. Visibility is typically 15-30 m and can be excellent in settled autumn and winter weather; it drops after the Myall Lakes and Wallis Lake systems discharge following heavy rain. Grey nurse sharks are present at almost any time of year here, with numbers varying seasonally, and the wrecks (Satara, Catterthun) require calm, low-current conditions for safe deep/technical diving.

Descend the shot line onto the bow, which is the most intact section and holds a number of interesting artefacts, then work aft along the collapsed sides where limited penetration is possible, allowing a minimum of 30 minutes to complete a circumnavigation of this large wreck before ascending for a staged safety stop given the depth.

Effectively a technical/deep-air or nitrox-extended dive depending on training and agency limits; plan staged decompression or strict no-decompression management; wreck specialty training strongly recommended given the scale and penetration opportunities.
