A missing woman who has not been seen for three days after setting out to climb one of the tallest mountains in Australia has sparked a desperate search effort.
Perth woman Lorjie Tonguia Bautista, 38, was last seen by herself when she left to climb Bluff Knoll in WA's Stirling Ranges at 4am on Tuesday.
There are 'grave concerns' for her as police and the State Emergency Service (SES) scour the wilderness that experienced freezing temperatures on Friday.

Ms Bautista told her family she was going to climb Bluff Knoll during her time off work.
She checked out of Stirling Range Retreat where she was staying early on Tuesday.
A retreat employee found her unattended Subaru hatchback at the Bluff Knoll car park after Ms Bautista's concerned husband called them.
A police helicopter using thermal imaging, civilian aircraft, dozens of police officers and SES volunteers and a tracker dog are scouring the cold wilderness for her.
Great Southern Police Senior Inspector Alex Ryan said they 'have grave concerns for her welfare'.
'Overnight temperatures are pretty low so we're concerned about that in relation to her welfare,' he said to The West Australian.
'But the terrain is particularly difficult. It's precipitous and very hard to search.'
They have also set up 'defined search areas' from the top of the mountain to the bottom that are being combed on foot.

Bluff Knoll is one of the few places with regular snowfall in Western Australia.
A temperature of -0.5C was recorded at the Stirling South weather station at the base of the mountain at 6am on Friday.
The peak of the mountain would have been much colder because of the higher altitude and wind-chill factor.
It is the highest peak of the Stirling Ranges in the Great Southern region of Western Australia.
At 1,099 metres tall, it is the 13th tallest peak in all of Australia.
