Las Vegas is a deep site off northern Moreton Island known mainly through UniDive, the University of Queensland dive club, which describes it as a very pretty rocky wall and reef full of nooks and crannies, in depths of 25 to 35 m and more. The club recommends it only for experienced divers with deep certification and suggests nitrox to make the most of the limited time available at those depths. marinelife.org.au lists it with the other northern reefs and repeats the advice that it is for experienced divers only. The attraction is the combination of intricate rock structure and the chance of big pelagic fish in open water.

The wall's cracks and ledges shelter crayfish, moray eels and reef fish, while schools of trevally, mackerel and other pelagics can sweep along the face on good days, and the northern Moreton area also produces grey nurse sharks, eagle rays and turtles. When the visibility is good – which is when this site should be dived – the wall stands out clearly against the blue. There is little published detail on the site's layout, and it is not on regular charter schedules, so most divers who see it will do so on a club trip or a special outer-reefs day with local guides.

It is best treated as a deep, exposed, advanced dive that rewards careful planning: short bottom time, conservative gas, a DSMB and a clear plan for current. Divers should expect water of about 19-21°C in winter and 24-27°C in summer, and allow for the long boat ride home after a deep dive when planning surface intervals and any second dive.

Boat access only. Brisbane charters leave from Manly Boat Harbour (Brisbane Scuba departs from the corner of Royal Esplanade and Davenport Drive, Manly) or from Scarborough Boat Harbour on the Redcliffe Peninsula, crossing Moreton Bay and running out through the North West Channel past Bulwer and Comboyuro Point to the northern tip of Moreton Island. Allow roughly 75-90 minutes from Manly in good conditions.

Sunshine Coast operators run south from The Wharf, Mooloolaba, in about 45 minutes. Private boats typically launch at Scarborough or Bribie Island; the open-water crossing around Cape Moreton is exposed and should only be attempted in settled weather with local knowledge.

Needs good conditions: calm seas (swell under about 1.5 m, winds under 15 knots, ideally westerly) and clear water. Open to ocean currents; aim for slack or light current. Best in winter when visibility is highest.

Northerly and north-easterly winds over 15 knots, and easterly groundswell, make the northern reefs uncomfortable, and the crossing around Cape Moreton is exposed to southerly change conditions. Morning departures ahead of the summer sea breeze are best.

Descend to the reef top at 25 m, follow the wall and its nooks at 28-30 m, watch the blue for pelagics, and begin the ascent with plenty of gas. Use nitrox and a DSMB.

Nitrox recommended (UniDive). Plan conservative gas reserves and carry a DSMB.

No regular commercial schedule found; dived by UniDive (UQ) and other Brisbane clubs, and occasionally by Brisbane operators on outer-reef days.
