Meet the site
Simmos sits on the big sandy patch off Lady Elliot's western side, the same sand plain that surrounds the Lighthouse and Scattered Bommies. The Oceanity guide notes that stingrays, turtles and eagle rays are commonly found here. It is essentially a sand and scattered-reef dive: rays feeding or resting in the sand, turtles crossing between reef patches and eagle rays gliding overhead. Garden eels and small coral outcrops add interest. The site is shallow and sheltered in the prevailing south-easterlies, making it suitable for new divers. Published information on this site is limited to the Oceanity guide to Lady Elliot's 28 named sites, so depths and layout given here are estimates based on neighbouring sites; the resort dive team will brief the specifics. All Lady Elliot sites lie within a Marine National Park (Green) Zone and are dived only with the resort's dive shop, on short boat rides of 10 minutes or less. Lady Elliot's reef is the southernmost part of the Great Barrier Reef, and its mix of sheltered western sand plains and exposed eastern walls means almost every site is within a few minutes of the next. Manta rays are most abundant from about May to August, humpback whales pass from July to October, and turtles nest on the island's beaches from November to March, so the same site can feel quite different depending on the season.
