Nothing spices up an election like a culinary gaffe.

In Britain, it was a bacon sarnie that rocked Ed Miliband’s campaign two years ago. For Bill Shorten, Australia’s opposition leader, it was a sausage sandwich.

Voting is compulsory in Australia and polling day is treated as something of a celebration with booths across the country accompanied by charity cake stalls and barbeques - the official polling map lets voters know which stations also have "sausage sizzles".
