The desperate search to locate a missing Belgian bushwalker continues in the remote Tasmanian wilderness, as police maintain the conditions she's lost in are not survivable.
Céline Cremer was reported missing June 26, with authorities finding her empty white Honda CRV a day later in the car park of the Philosopher Falls walking track, located in the state's north-west near Waratah.
The 31-year-old is believed to have been trekking in the area before she vanished, with freezing conditions, snow and rain, hitting in the days since.
Police yesterday conducted a swift water search at Philosopher Falls in a bid to locate Cremer, but no sign of the missing traveller was found.
Inspector Anthea Maingay has appealed for anyone who may have seen the woman to come forward.
"Celine's car has been in the Philosopher Falls car park since at least Tuesday, 20 June and last week we received expert medical advice indicating Celine could not have survived the conditions she has been exposed to since then," she said.
"Our information to date indicates Celine could have been in the area even earlier than that, and we're asking anyone who was in the Philosopher Falls area on the 17 and 18 June to contact us, whether they think they have relevant information or not."
"We are continuing to review the search effort so far to determine next steps, and our thoughts continue to be with Celine's family and loved ones at this difficult time."
Over the past few days search crews have focused their efforts around the Philosopher Falls waterfall.
Cremer was due to board the Spirit of Tasmania on June 21 to venture to the mainland.
She never arrived at the terminal.
The last reported sighting of her was in the nearby town of Waratah on June 17.
Cremer's sister Amélie told 9news.com.au last week the anxious wait is the "most difficult thing.
"We are helpless here and we just want to know," she said.
"Just open your eyes and if you have time, please for our family, go and search with the police," she said.
"I keep hope to find her, no matter the issue, I just want to know where she is."
