Canadian police have confirmed that a backpack and jacket found near a mobile phone belonging to Alison Raspa are also those of the Perth woman, who has been missing for nearly two weeks.
Ms Raspa was last seen at Three Below bar in Whistler, B.C., on Canada's west coast, about 11.30pm on November 22.
Her phone was found the following morning in a lakeside park, some five kilometres away.
Police have told AAP that a jacket and backpack had also been found in the "same general area" by a member of the public.
"It took us a little time to confirm (the backpack) was hers and such, but we are confident that it's hers," Staff Sergeant Paul Hayes, of the Royal Canadian Mounted Police in Whistler, told AAP.
He said police continue to believe Raspa was not the victim of foul play.
An unnamed male employee of Three Below disputed rumours a fight took place outside the bar on the night of November 22.
"I know because I was here that night and I have told police everything that happened that night and handed over all the security camera footage," he told news corp.
Police do not believe Raspa walked from the bar, near the ski resort's gondolas, to Alpha Lake Park in Creekside, where her belongings were found.
Hayes earlier said police "had some thoughts" as to how Raspa travelled between the two places, but would not say if they were seeking someone who may have driven her.
Police and search and rescue personnel have spent days searching the Creekside area, with divers and fire crews searching nearby lakes without success.
Members of Raspa's family arrived in B.C. last week. Her brother, Steve, joined a small walking search by friends and community members on Friday.
Raspa's family has declined to speak to media.
