Hundreds of protesters have marched to call on the federal government to scrap a proposed nuclear waste dump on South Australia's Eyre Peninsula at a rally on Sunday.
The farming property Napandee near the town of Kimba was announced as the site of the radioactive facility on Saturday.
The rally held in Kimba brought together locals and visitors opposed to the dump, backed by indigenous and environmental groups.
The No Radioactive Waste on Agricultural Land in Kimba or SA committee criticised the timing of the announcement.
"Yesterday was a very emotional day for a lot of us," spokeswoman Kellie Hunt said.
"The minister knew that we had the rally happening today and he certainly showed a lack of respect by not waiting to hear what those who are opposed to the facility have to say."
Organisers of the march said the announcement was just the beginning of a long battle before the installation opens.
The group's estimations forecast their window of opportunity to push their claims can extend for a couple of years while all licenses are granted and the plant starts.
"Those opposed to the facility have had no choice but to fight, at every opportunity, for our legitimate concerns to be heard," president Peter Woolford said.
The community consultation process that led to this decision returned a 62 per cent vote in favour of the facility.
Those opposed to the dump, however, claim the voting was flawed.
"People that live very close to where the facility is planned to start weren't entitled to vote because of where the council boundaries fall," Ms Hunt said.
"This is not a Kimba issue only. South Australia should have a say on this."
The group claims that if South Australia's legislation prohibiting the building of nuclear waste facilities is to be overturned, the whole state should cast a vote on that decision.
Jeff Baldock, who owns the Napandee site, said the project would boost the community and attract new industry to the area.
"There are a couple of large projects that are being considered now that would not have even been talked about if it wasn't for the fact that we may have this money," he said.
Federal Resources Minister Matthew Canavan said a decision on the site would be announced soon.
