A major marine search operation has intensified this morning after an inexperienced kayaker went missing off Point Peron.

Ian Steven Tolli was last spotted about 1.30pm yesterday in an orange kayak.

A kayak which is believed to belong to Mr Tolli was located about 300 metres from the coast by fisherman, near Kwinana Beach.

Police, Surf Lifesaving WA and marine rescue crews are searching the area via air, land and sea.

Surf life savers on jet skis took off from the Point Peron boat ramp this morning, joined by eight sea rescue boats including the water police vessel.

Rockingham police will conduct shoreline patrols on foot and the police airwing helicopter will search the water from the air.

The 54-year-old is described as 188cm tall with light skin and short brown hair, and it’s believed he is wearing a Hawaiian shirt and shorts.

Police say he was wearing an old life jacket, but he wasn’t an experienced kayaker.
