The dive sites are generally located around Rottnest Island and the Stragglers and many of them are exclusive to the UEC having been found in over 60 years of exploration. The actual sites dived on the day may differ from those advertised depending on weather and sea conditions. All boat dive trips are double dives, alternating between Saturdays and Sundays, unless advertised otherwise, with a surface interval over lunchtime. The boat will often go into one of the sheltered bays around Rottnest for lunch (note lunch is not provided). The boat will return to the Marina usually between 3 and 4pm depending on which sites have been visited.
