Extensive coastline and waterway searches over the last two days have led police to the conclusion that Shaun Hogarth has not survived the swamping of the 3.5m dinghy that tipped him and three other men into the upper harbour on Tuesday night.

'Police are satisfied that if Mr Hogarth was still alive in the water or had made it to land he would have been located by searchers,” says Inspector Karl Wright-St Clair.

The search of Shaun Hogarth's body continues.

'Police now believe it is unlikely that Mr Hogath has survived the incident and have shifted their focus to recovering Mr Hogarth's body.”

The Police Dive Team and Navy divers using sonar equipment will continue searching the area where police believe the vessel was swamped. The conditions on the water today will be testing for the team given the weather and the tidal nature of the area.

"Our thoughts are with the family. At this time they have asked me to convey that they are seeking privacy to come to terms with the situation," says Karl.

Police are also still trying to locate 22-year-old Liam Kane who made it to shore but then disappeared, and are keen to hear from anyone who might know where he is.
