The Kimba community will get up to $2 million in additional grants through a new Community Benefit Program announced this week.
The federal program is the second of its kind in Kimba, with 33 projects funded in the district in the previous round.
Local infrastructure upgrades, services, apprenticeships and mental health initiatives are some of the projects that will be eligible for the funding, aimed at assisting communities that have been considering hosting the National Radioactive Waste Management Facility.
The announcement comes as the Kimba community votes on whether it supports the facility, with the ballot to close on November 7.
The ballot will then be considered in conjunction with business, neighbour and traditional owner surveys, direct feedback and submissions made over the past few years of consultation with the community.
Resources Minister Matt Canavan said the new program, which will also see $2 million allocated to the community around Wallerberdina Station, was in response to community consultation and delays in the site selection process over the past year.
"We recognise that the communities have engaged in debate in good faith and we remain committed to supporting them through the site selection process," he said.
"This investment will support the communities as well as deliver projects and initiatives that can further diversify the local economies."
The money will be allocated to the two communities regardless of whether they are chosen as the host for the facility.
The host community will be allocated an additional $31 million Community Development Package.
Mr Canavan said he had been listening to the communities and he would support them regardless of the outcome.
"My commitment and connection to these communities will extend beyond the result of the upcoming vote and is not dependent on the result of that vote," he said.
"The Flinders Ranges and Kimba are great country places that I have had the pleasure to get to know better through this process."
The Kimba District Council and Kimba Consultative Committee will soon be consulted on draft guidelines for the new program, with details on how to apply for funding to be provided at business.gov.au when available.
