Bill Shorten may need a few more lessons on eating a democracy sausage before next year's federal election.

The Melbourne-based federal Labor leader was voting in the Victorian election on Saturday when he was snapped taking a bite of the sausage sandwich. And it was awkward.

Although he managed to bite the end, unlike the time he bit the middle of the sausage sandwich during the 2016 federal election.

On Saturday wife Chloe was on hand to show him the way, with Mr Shorten chomping into the barbecue treat.

For the record, Mr Shorten doesn't care if the onions are on top or the bottom of the sausage, he just like onions.
