The group is drawing up a rescission motion claiming council's plan to spend up to $15,000 a year on an Aboriginal project worker is discriminatory and unnecessary.

In a heated debate at council on Wednesday night, the group attacked chairman of the Aboriginal advisory committee Cr Larry Whipper over the idea, which was eventually given the nod in a narrow 6-5 count.

"This just seems like an ego trip for Cr Whipper and it's an absolute waste of money and completely out of the question," Cr David Wood said.

"There are many more groups that are disadvantaged in the shire - what about our new immigrants from Vietnam and the Middle East."

Other councillors bristled about the position, claiming it was breaking council's own equal opportunity stance by being available only to Aborigines.

"This is divisive and it should be open to the best candidate irrespective of their race, colour or creed," Cr Nick Campbell-Jones said.

"If we worded it the other way around we'd be in all sorts of strife."

But Cr Whipper was quick to defend the plan, accusing opposition councillors of outdated thinking.

"I'm absolutely flabbergasted and it's a step back into the dark ages," Cr Whipper said.

"There are a number of issues like health and housing within the local Aboriginal community that need to be addressed.

"I'm disappointed with some of the comments made by other councillors and that sort of hostility reflects very poorly on council.

"There are people suffering in this community and they are Aboriginal and they would consider it an insult to reject this opportunity.

"The last time they put their hands out in a gesture of friendship the country was taken off them, and they deserve to be listened to and heard this time."

There are currently about 420 identified Aborigines in Wingecarribee Shire.

The dissenting councillors fired in an amendment to the original motion but it was defeated, prompting some angry replies from the group.

"If anyone can show me where we've failed the Aboriginal people in this shire I hope they will advise me," Cr Gordon Lewis said.

"When we start singling groups out for special treatment we run into trouble and that's where we're going wrong as a country."
