Remains belong to WA trekker: autopsy

Early autopsy results suggest skeletal remains discovered on a Nepalese mountainside belong to missing West Australian man Matt Allpress.

Friends and family raised the alarm in November after the 23-year-old failed to arrive in Sydney following a solo 10-day trek in the country's Annapurna ranges.

His remains were found on May 10 and his parents, Margaret and Mark Allpress, travelled to Pokhara police station in Nepal last week, where they confirmed clothing and personal items found nearby belonged to their son.

On Thursday, Mrs Allpress went to the Kathmandu hospital where doctors have been examining the remains.

"The doctors advised that their preliminary findings were that the remains were of Matthew Allpress based on the dental and medical records provided by the family," read a message posted on the Find Matt Facebook page on Friday evening.

"Mark and Margaret thank everyone for their thoughts and prayers ... they do appreciate your support."

A 15-strong team of Nepalese police will now travel to the mountainous region where the remains were discovered in a bid to retrieve Mr Allpress's remaining belongings.

Tributes have begun to flow for the young adventurer on social media.

"Matthew you were (a) wonderful young man with your whole life ahead of you. May you now enjoy life amongst the stars," Donna Garvey Noonan wrote.

Another friend, Jane Suckling, wrote that Mr Allpress had left a "hole in all of the hearts he touched".
