The family farm appears to be headed for extinction.
The latest farm census from the Australian Bureau of Statistics shows only 102,616 families made their living from farming in 2006.
More than 10,000 had given up farming in the previous five years.
About 2300 families gave up farming in Victoria, bringing the total down to 25,658.
The adults in the families that remained were relatively old, with the typical age of adults on farms reaching 52.
The proportion of farmers above the retirement age of 65 jumped from 15pc to 18pc between the two censuses.
The latest census says more than half of family farmers worked more than 49 hours a week, compared with 18pc of people in the overall population.
National Farmers Federation acting chief executive Denita Wawn said the number of farms had been falling for some time.
"Back seven years ago there were 170,000, now there are 120,000, but what's important is the land mass has remained the same."
