SA-Best ahead in key seats: poll

Nick Xenophon and his SA-Best party are on track to win at least three seats at this year's state election, a new poll shows.

The Galaxy poll, published in the Advertiser, surveyed key seats in Adelaide's south and east, finding Mr Xenophon would win 37 per cent of the primary vote in Hartley ahead of incumbent Liberal MP Vincent Tarzia on 32 per cent.

SA-Best is also ahead in the seat of Mawson, currently held by Tourism Minister Leon Bignell, with 38 per cent of the primary vote and in Hurtle Vale with 33 per cent.

Mr Xenophon has previously said his party will have around 30 candidates for the March 17 election.

The poll of just over 1000 people was taken between January 11 and 14.
