Police launched a more targeted search of Karroun Hill Nature Reserve after they found the van she had been travelling in bogged in bushland in the reserve, 35km off a main track.

“First and foremost, I want to express a huge thank you from the bottom of my heart — a thank you that truly comes from the depth of my soul! For all the incredible support during the search for me,” she said on Monday.

‘Deeply impressed’

“Western Australia has taught me what it really means to be part of a true community. Here, humanity, solidarity, and care for one another are what truly matter — and in the end, that’s what counts most.”

Wilga said while her experience had prompted dark moments, she said she believed she survived only thanks to an “incredible outpouring of support”.

“The thought of all the people who believed in me, searched for me, and kept hoping for me gave me the strength to carry on during my darkest moments. For this, I want to say thank you from the bottom of my heart.”

Wilga explains why she left her vehicle

Wilga acknowledged the curiosity around her decision to walk away from her vehicle.

Wilga escaped serious physical injury, coming away from the ordeal with cuts and bruises and suffering from dehydration and fatigue.
