Fair Trading New South Wales says Aboriginal tenants in the state's south east are facing discrimination.

It signed a Memorandum of Understanding with the Anti-Discrimination Board of NSW to protect indigenous consumers this week.

"Fair Trading has become aware over recent times of discrimination against indigenous communities and that has occurred in various parts of NSW including the south east region of the state," the Fair Trading Commissioner, Rod Stowe, said.

"Our particular concern is indigenous people sometimes find themselves discriminated against when it comes to leasing property and the like."

Mr Stowe said Fair Trading was working to prevent racism by educating real estate agents, landlords and tenants about their rights and responsibilities.

"I think it is about trying to make sure that we educate people that it is against the law to discriminate against others when it comes to supplying goods and services and that people should have equal access in all of these areas," he said.

"There are some fairly stiff penalties for failing to comply with the law."

He said Aboriginal people in the south east who believed they had been discriminated against should contact Fair Trading.

"We do have indigenous officers who can deal with their complaint and we have a free call number they can ring, it is 1800 500 330," he said.

"We in the first instance will try to resolve a dispute.

"However, if there are breaches of legislation then we will pursue those in collaboration with the Anti-Discrimination Board."
