Votes for the Kimba community ballot on the National Radioactive Waste Management Facility need to be sent as soon as possible, with just under a week remaining until the vote closes.
Ballots must be returned to the Australian Electoral Commission (AEC) before the morning of Thursday, November 7.
Voter turnout for the postal ballot has been strong so far, with 84.22 per cent of possible votes already received by the AEC.
694 of the 824 ballots sent to eligible voters in the Kimba district had been returned as of Thursday morning, October 31.
The official count of the votes will begin late morning on November 7.
The AEC has until November 11 to finish the count, but it is likely to provide the official result to the Kimba District Council by the end of Friday November 8.
