Chimanan's Hat offers something rare: a shallow artificial reef where you can meet Australian fur seals in waters calm enough for your first dive. The site sits in depths between 1 and 6 metres, making it perfect for building confidence whilst getting genuinely exciting wildlife encounters. The artificial reef structure attracts smooth rays gliding along the sandy patches, whilst bottlenose and common dolphins occasionally pass through the area. The mild current means you won't be fighting to hold position, though visibility can vary significantly depending on conditions. You'll need to reach the site by boat, and several local operators run guided tours which make sense for newer divers. The seal interactions are the real draw here: these curious animals often approach divers, though you'll need to let them come to you rather than chasing them. Be aware that boat traffic moves through the area, so stay close to your guide and listen carefully during the briefing. Summer months from December through February typically offer the best conditions, when the water is warmer and wildlife activity peaks around the reef structure.
