Science makes bunny of Aussie hat firm
They have kept the rain and sun off the heads of generations of Australians but the makers of the country's distinctive Akubra bush hats have been hit by a dramatic shortfall in their product's main component - rabbit skins.
A virus introduced to control rabbit numbers seven years ago has been far too successful for Akubra's liking, with the company forced to import skins from rabbit farms in China and Europe.
According to the family-run firm, the imported pelts are far inferior to the fur of wild rabbits which produce a finer grade of felt.
Akubra produces 250,000 hats a year, many for the tourist and overseas market, but Australia's dwindling professional rabbit shooters cannot keep up with demand and the use of local skins has halved in the past two years.
Calicivirus was released into the wild in 1995 in an attempt to control the number of rabbits, which over decades have reached plague proportions.
At their peak there were an estimated 300 million wild rabbits in Australia, responsible for A$600 million (about HK$2.45 billion) in damage to crops and soil erosion a year.
