Albany Sergeant Vaughn Mackay said Ms Duckett was spotted at the site about 11.45am on April 2 and is believed to have travelled alone from the Perth metropolitan area to Albany the previous day.

Authorities have shut public access to The Gap while an extensive search continues across land and sea.

Water and ground crews, including local police, the Police Air Wing, drones and Water Police, are scouring the rugged coastline.

The Department of Biodiversity, Conservation and Attractions and the City of Albany are also assisting with the operation.

Ms Duckett is described as about 171cm tall with a medium build. She was last seen wearing glasses, a dark-green jumper, light-coloured pants and black shoes.

“Ms Duckett’s welfare is our main priority at this time,” Sergeant Mackay said.

“We are very, very keen to hear from anyone who may have seen Ms Duckett in the area, [or] may have any information in regards to whereabouts.

“The Gap Natural Bridge is a well-visited natural tourist spot.

“There would no doubt have been people present when she certainly arrived, and certainly during the day, whilst we suspect that she may have been there in that park.”
