London: It is the smell every Australian voter associates with election day and on Saturday the smell of sizzling sausages wafted down Aldwych in central London.

Democracy sausage has become such a fixture at Australian elections that it's even earned its own emoji on Twitter.

But Australians in the UK have been deprived of their sausage sizzle because of Westminster Council's draconian regulations forbidding "ad-hoc" mobile food trading - until this year.

On Saturday, the High Commission combined forces with the Royal Flying Doctor's service to hold a barbeque on the steps of the building, which is technically Australian and not British territory.
