Grey nomads are biggest BlazeAid volunteersLucy Barbour, Tuesday September 10, 2013 - 13:46 EST
More than 3,500 people volunteered to help farmers rebuild fences after fires and floods on Australia's east coast last summer.
The BlazeAid organisation has released the numbers of all those who've assisted since the fires in Tasmania, New South Wales and Victoria, and the floods in Queensland.
BlazeAid's Mary Howarth says 75 per cent of volunteers were grey nomads.
"So altogether they did 29,670 volunteer days and that's absolutely incredible," she said.
"And the numbers of properties worked on was 810.
"And the fencing cleared was 1,350 kilometres, and rebuilt is 1460 kilometres, so that's a lot of work."
