The NSW Premier was snapped eating a democracy sausage sans bread on the campaign trail with Liberal candidate James Griffin at Manly West Primary School, in a move that drew the attention of state opposition leader Luke Foley.

"Unlike Gladys, I prefer my sausage sandwich with bread," Foley gleefully tweeted.

Ms Berejiklian's peculiar choice was reminiscent of another key sausage moment during the 2016 federal election campaign, when a seemingly confused Bill Shorten tucked into his roll in a manner that left onlookers stunned.

Last July, Mr Shorten infamously took a 'sideways' bite of his sausage sandwich at Strathfield North Public School, before turning away from cameras to tackle the remainder.

"The taste of democracy," the Labor leader then declared.

Perhaps the only constant amid a tumultuous string of election days, the humble sausage sizzle has continued to rise in prominence, with 'democracy sausage' being crowned Australia's Word of the Year by the Australian National Dictionary Centre in 2016.

However, Ms Berejiklian may well have been practising what she preached, after the premier in February announced plans to overhaul school canteens, ditching Space Food Sticks in favour of freshly-made lunchbox options, including more fruit and vegetables.

"I had too many sausage rolls and cream buns and Zooper Doopers [at school]," she told the ABC.

The Liberal Party was expecting large swings against it after a campaign marred by questions over the integrity of two candidates, James Griffin and Felicity Wilson, and pressure over issues including traffic and council amalgamations.
