The family of 20-year-old Ballantyne Forder, from Perth are desperate for any information of her whearabouts.
Ballantyne was working in an orphanage in Nepal when a devastating 7.8 magnitude earthquake hit on Saturday.
She is among five Australians listed as missing after the earthquake struck Nepal and north India, killing more than 1,300 people and triggering a fatal avalanche on Mount Everest.

In Nepal, 30 out of 75 districts were affected by the quake.

An estimated 4.6 million people in the region were exposed to tremors from the Nepal earthquake.
The other Australians missing, according to the Red Cross website, are Zachary Sheridan, 20 of Adelaide, a 59-year-old woman and 18-year-old man from Melbourne and a 43-year-old man.
Zachary is the younger brother of Packed to The Rafters actor, Hugh Sheridan.
Ballantyneโs sister, Amanda-Sue Markham, has been using social media to ask for assistance to find her โBillie.โ
โ#auspol Please find my baby sister missing in Kathmandu,โ she wrote this morning.
โBillie travelled a long way to take care of those children. My guess is she has stayed with them.โ
Around 700 Australians registered with DFAT as travelling in Nepal.
More to come.
