REVEALED: Marshall falls behind in early polling

In the Upper House, 9 per cent of respondents favoured the Greens, while One Nation – fighting its first state campaign since 2006 – picked up 5 per cent, as did the Nick Xenophon-founded SA Best.

Former Xenophon acolyte John Darley’s Advance SA, which has announced cross-border community advocate Paula Gust as its prime Legislative Council candidate, garnered one per cent, with 13 per cent of respondents identifying other crossbench options.

These could include a glut of minor parties and independents, with Family First seeking to re-establish its electoral credentials under former Labor MPs Tom Kenyon and Jack Snelling, and former Director of Public Prosecutions Stephen Pallaras seeking election under his Real Change SA banner.

The Australia Institute’s SA director Noah Schultz-Byard said the results of the first statewide poll since the campaign began showed “it will be a hard-fought campaign that may well come down to the wire”.

“While there are mixed opinions in the community regarding the decision to open the state’s border in November, there is a strong sentiment that the Government should have done more to prepare the state for the subsequent influx of COVID-19,” he said.

“The perception that South Australia was not adequately prepared when the borders were opened is held across the political spectrum, with a majority of voters for all parties agreeing more should have been done.”

The Institute’s previous poll in September identified health – and the COVID pandemic – as key battlegrounds for the forthcoming election, but Schultz-Byard emphasised thxjmtzywat “polling doesn’t predict political outcomes and is simply a snapshot of sentiment at one time”.

Nonetheless, he said, “if these voting intention results are reflected as a uniform swing at the election, Labor would win the four seats required to form a majority in the lower house”.

“Of course, the election is still a month away and anything can happen on the day,” he added.
