Premier Colin Barnett said the impact of the 7.8 magnitude earthquake that struck on April 25 and its series of aftershocks had been felt around the world.
“With thousands killed and thousands more injured or without access to shelter or clean water and adequate food supplies, every contribution will help in the recovery effort under way in the region,” Mr Barnett said.
“Many West Australians had relatives or friends in the region or have previously travelled there themselves and all will be deeply distressed at the devastation caused by this natural disaster.”
The donation on behalf of Western Australia would go towards providing first aid, emergency shelter, food supplies and assistance to government rescue and recovery efforts.
The Premier said the recovery effort would be a long process and acknowledged the crucial work being done by aid agencies such as the Red Cross.
Mr Barnett said WA Health employee Dr Andrew Robertson, a trained leader for Australian Medical Assistance Teams and chair of the National Health Emergency Management Committee, had also been deployed to Kathmandu as part of a small medical assistance team.
The State Government has contributed to appeals for several natural disasters in Australia and overseas, including the Victorian bushfires in 2009, the Queensland floods, the Japanese and New Zealand earthquakes in 2011, and the Tasmanian and New South Wales bushfires in 2013.
