The message was loud and clear as hundreds of people voiced their opposition to the forced closure of Aboriginal communities during a march through Wollongong's CBD on Friday.

"Close the gap but not the community" and "There's no pride in genocide" were among the slogans chanted by supporters who joined a rally that coincided with similar protests across the country.

Young and old, Aboriginal and non-Aboriginal, the group carried placards, banners and a couple of megaphones as they marched from MacCabe Park to Burelli Street's Civic Plaza via Crown Street Mall in a show of solidarity.

The public rallies across the nation were prompted by a West Australian government plan to stop funding services for a number of that state's remote Aboriginal communities.

"It [the rally] has been a great occasion for the support of our Aboriginal people, Aboriginal communities [in the] outback that are going through this stupid, stupid practice that they are looking to do," well-respected Illawarra Aboriginal community leader Richard Davis told the estimated 400-strong crowd at the plaza. "We're living in 2015, not the 1950s; we need to make sure we keep this fight going because without that, these governments are going to do whatever they want."

Mr Davis said he was "a proud Aboriginal man" and a member of the Illawarra Aboriginal Corporation, which had been operating for almost 40 years.

"I'm going to make sure that I continue to fight for our rights and recognition in our community, in our country," he said.

"Because, at the end of the day, we are traditional owners, we are the first people of this nation and whatever people say or want to think, bad luck, that's us, we're here, we're not going anywhere, so get used to it."

The statement was met with resounding applause from the crowd.

Photos of the rally, which was also attended by Throsby MP Stephen Jones and South Coast Labour Council secretary Arthur Rorris, were shared using the #SOSBlakAustralia hashtag.
