Resting at depths between 44 and 48 metres, the site requires boat access and is suitable only for experienced technical divers. The wreck presents an overhead environment that necessitates careful gas management and decompression planning. Visibility at the site is highly variable, ranging from 5 to 40 metres, while currents remain mild. Due to the significant depth, divers must account for nitrogen narcosis and entanglement risks. The site is accessible for night diving, with typical bottom times around 30 minutes. Water temperatures fluctuate between 17C and 21C throughout the year.

Patonga Creek is a shallow, sheltered estuary site in New South Wales, offering a muck diving and snorkelling environment. The topography consists of seagrass meadows and sandy patches, with depths ranging from 0 to 5 metres. Access is straightforward from a sandy beach, making it suitable for beginners. Tidal flow can create currents, so snorkelling around high tide is recommended for improved visibility and calmer conditions. Hazards include boat traffic, jellyfish, rip currents, and stonefish. Divers and snorkellers should use a surface marker buoy due to boat activity. Facilities at the site include parking, toilets, and a cafe.

The Wall at Long Reef is a reef and wall dive site suitable for beginners, featuring depths between 8 and 15 metres. The wall structure provides a clear navigation point for divers. Conditions are variable, with visibility typically ranging from 10 to 25 metres and water temperatures between 18C and 24C. Access is by boat, and divers should carefully assess surf conditions before entry. Once submerged, staying close to the reef wall helps manage strong currents and maintain visibility. Dives typically last around 35 minutes. It is recommended to time dives for slack water and confirm current forecasts with your operator before heading out.

Umina Beach, located at Pearl Beach, provides a shallow reef environment suitable for beginners. Divers and snorkellers can access the site directly from the shore, with the reef located approximately 50 metres out. Depths range from 2 to 10 metres, with an average of 6 metres.
