GoPro footage from the Himalayan expedition where eight climbers including a Sydney woman were killed in an avalanche late in May has been released by Indian authorities.

The Indo-Tibetan Border Police (ITBP), which found the device during a mission to retrieve the climbers' bodies, published the short video on Twitter.

"Last visuals of the mountaineers' team near the summit on unnamed peak near the #NandaDevi east," the ITBP wrote.

"ITBP search team of mountaineers found the memory video device at 19K ft [5800 metres] while they were searching the area where bodies were spotted."
