[1] At 11:30 pm on Wednesday, 30 July 1997, a landslide destroyed the Bimbadeen and Carinya Lodges at the Thredbo Alpine Village in New South Wales.
The landslide destroyed the support for Alpine Way road, which then collapsed, and sheared the western half of Carinya from its foundations.
[2] The detached structure slid downhill and crossed Bobuck Lane before colliding with the Bimbadeen Ski Lodge at high speed, destroying both.
Witnesses reported hearing "a whoosh of air, a crack and a sound like a freight train rushing down the hill".
John Cameron, a member of Brindabella Ski Club, who was alone in Carinya, along with 17 residents in Bimbadeen, lost their lives.
Within 10-20 minutes of the landslide, New South Wales Fire Brigades Communication Centre at Wollongong received emergency calls from the lodge at Thredbo.
At 7:30 am, a forward medical command post was established, set up in a lodge located 50 metres (164 feet) from the site of the disaster.
During the day, several environmental issues were identified such as water and sewerage being cut off to the site, and some diesel fuel seeping into Thredbo Creek.
They had not completely given up hope, but Assistant Police Commissioner Ken Moroney told reporters; "I think at this stage the chances are quite remote.
Police Superintendent Charlie Sanderson explained the difficulty of extracting Diver because they could not risk the concrete slab falling on top of him.
[7] Due to the risk of the overlying concrete crushing Diver, rescuers began digging a tunnel 16 metres (52 ft) long from the eastern side of the slope.
[2] In 1998, three terraces with gabions and reinforced fill were constructed on the site and the Alpine Way was rebuilt with upslope retaining walls.
The site along with a section of the Alpine Way is now monitored with 25 inclinometers, to detect any slope movement, and 12 piezometers, to keep track of water flow in the soil.
[5] As of December 2004, the State Government of New South Wales spent $40 million in out-of-court settlements with 91 businesses and individuals after the incident.
[10] On 2 December 2004, the Supreme Court judgment blamed the leaking water main pipe and the Alpine Way, which was built on a road full of debris, as the cause of the disaster.
[10] Soil creep had caused the main to fracture, which had saturated the already unstable slope that supported the road above Carinya.
[1][3] Once the power stations were completed, the Authority upgraded the road with fill and planted vegetation on the downhill hillside.
[1] A memorial service was held in 2007 to mark the tenth anniversary of the events, which included a flare run down the mountain after sunset.
