Police extend search to find Lake Tuggeranong windsurfer

The 56-year-old is a draughtsman employed by the Australian National University.

Friends said the Filipino-born Canberra resident was an experienced windsurfer who was familiar with the area he went missing in. An ACT Policing spokeswoman said a Rural Fire Service helicopter would take over the aerial search on Tuesday, after the SnowyHydro Southcare helicopter joined the search late on Monday afternoon

"Water-based operations will cease at sunset [Monday], and will recommence at 6am tomorrow morning," the spokeswoman said.

"Shore-based patrols will occur throughout the night."

Police divers were back on the scene at first light on Monday morning to resume the search. The ACT SES and police boats and divers searched the water and the shores of Lake Tuggeranong throughout the day.

Australian Federal Police, including boat crews and divers, began the search after a man was reported to have come off his board 60 metres from a dog park on the lake's eastern side about 4pm on Sunday.

Mr Dungca's board was found washed up on shore about 6pm on Sunday.

Paul Sjoberg, a friend and co-worker of Mr Dungca, said he had failed to show up for work on Monday. ''People rang me from work today and Bobby was supposed to be at work but he didn't turn up,'' he said. ''Bobby religiously turns up.''

He said Mr Dungca's partner had visited the search area. ''He's a top guy, a really nice guy,'' Mr Sjoberg said. ''He is extremely fit and strong so he might have thought he didn't need to wear a life jacket.''

Police have urged anyone who witnessed the incident or has any information to contact Crime Stoppers on 1800 333 000 or at act.crimestoppers.com.au.

[Sunday] were extremely windy, there was a north-westerly wind that was quite hot and blowing a gale,'' he said.

"The male was a very experienced windsurfer. I've been briefed [that he had] over 30 years' experience in windsurfing in different conditions and different water environments."

Sergeant Serbatoio said the lake was not a dangerous place, but urged recreational users to take safety precautions before heading out on the water.

"At this stage it appears the male windsurfer was not wearing a personal floatation device," he said.

The search comes during a busy 48 hours for emergency services as Australians head to the water in hot weather. A search has been suspended for a rock fisherman who was swept into the ocean at Jervis Bay.

Police don't believe the man was wearing a lifejacket.
