Nathalie Casal: Update in search of doctor who vanished during hike on Bibbulmun Track in Western Australia

Police have revealed there has been a possible sighting of a doctor who disappeared three months ago while walking along a popular trail with a large group of people.

Dr. Nathalie Casal informed her family last December that she would be hiking the Bibbulmun Track in Western Australia with a group and may be out of touch for some time.

The Bibbulmun Track is a long-distance 1,000 kilometer trail that stretches from Kalamunda, east of Perth, to Albany.

Police believe the 71-year-old may have started his walk from Mundaring, a popular starting point for many of the walking trails in the area east of Perth.

She has not been seen since she left on the hike in December more than three months ago.

Western Australian police have since received information that Dr. Casal may have stopped at Northcliffe for supplies on the afternoon of 14 March.

“If this information is correct, it is believed that Dr Casal would now be somewhere between Northcliffe and Walpole, en route to Albany,” a spokesman said.

Her family first reported her missing two weeks ago on March 7.

A police statement issued last Thursday said Dr. Casal had not been in contact with her family since she disappeared.

“This is out of character for Dr Casal and prompted her family to contact the police,” a spokesman said.

Police are urging people in the area between Northcliffe and Walpole to report any sightings.

Dr. Casal is described as being approximately 157cm tall, of slim build, with short gray hair and brown eyes.

She is listed online as a GP based in Joondalup, which is 26km north of Perth’s CBD.

Anyone who has seen her or has information about her whereabouts is urged to contact the police immediately on 131 444.
