The electoral commission warns that a result in Saturday's Bragg by-election will take a long time, but voters in Adelaide's eastern suburbs are going to the polls for the third time this year.
The by-election was triggered by the departure of South Australia's former attorney-general Vickie Chapman, who left politics after the Liberals lost the state election earlier this year.
Bragg, which overs most of the City of Burnside and overlaps with Sturt on a federal level, has been held by the Liberal Party since the seat was created in 1970.
Jack Batty, who previously worked for Christopher Pyne and George Brandis, is the candidate of the Liberal Party.
I don't think there is any such thing as a safe Liberal seat anymore, so we're not taking anything for granted, Mr Batty said yesterday.
We've been out working hard over the course of the campaign, fronting up and listening to our community about what matters most to them. Batty said he understood that voters were frustrated about having to go to the polls for the third time in four months.
He said that people are frustrated about the timing of her departure from Vickie Chapman's decision to leave, but it is also an opportunity, as frustrating as some people might find it.
It's an opportunity for us to renew our team and get a strong voice in this new Liberal team. Labor's candidate Alice Rolls, a lawyer who has worked for two of Australia's largest commercial law firms, has been working from home this week after her daughter tested positive for COVID - 19.
It's not what we planned and like so many other young families around South Australia, we are juggling COVID and kids and work, so we made the most of it, Rolls said on Friday.
In the last seven days, pivot the campaign slightly changed to me being at home, ringing around the electorate, making calls and introducing myself, and seeing if people have any issues they would like to raise with me. Ms Rolls said the community had been welcoming towards her throughout the campaign.
She said that the community has not been door-knocked for nearly 40 years because people are saying that they have not been door-knocked.
They have been very receptive to me doing exactly that. The Greens candidate and history teacher Daryl McCann is representing Family First.
More than 4,500 early votes have been cast in the by-election, with a similar number of postal vote applications sent out by the Electoral Commission of South Australia.
James Trebilcock, ECSA's director of communications, said that the Bragg by-election has continued the trend we saw in the recent state election of a higher rate of people voting early or by post.
Over a third of the votes in the Bragg by-election are declaration votes and won't be counted until Monday.
The results for the Bragg by-election may not be known until next week, after the declaration votes are counted. The Electoral Act specifies that ordinary votes cast on polling day are counted first and declaration votes are not counted until the Monday after the polling day.
