Bill Williams runs the South Wagga Newsagency on Baylis Street and said allowing Coles and Woolworths to sell lottery tickets would increase problem gambling.

It comes as a five-year moratorium banning other retailers from selling lottery products is due to expire in April.

Mr Williams attended a meeting of the Wagga and district members of the Newsagency Association of NSW and ACT (NANA) on Wednesday night.

He said members voiced their concerns about the future of the industry.

"There has been a positive outcry from the community. It's been very pleasing, from our point of view," he said. "We'd like to encourage people to get behind us and support us."

NANA has circulated a petition gathering signatures against the move, already drawing more than 1000 signatures across Wagga newsagents.

The meeting was designed to outline the association's next steps, which includes lobbying Wagga MP Daryl Maguire as well as Riverina MP Michael McCormack.

Mr Williams fears if the concerns of newsagents fall on deaf ears, gambling problems could grow.

According to the Australian Medical Association, Australians are already among the most prolific gamblers in the world.

"I'm sure there will be proper regulations but it just makes the accessibility of gambling far too easy," Mr Williams said.

"It's up to us to make sure we can reflect to the community that we (the newsagents) are the people for proper delivery."

Mr Williams said maintaining the right to sell lottery tickets exclusively was the biggest challenge the industry had faced since media deregulation, which allowed newspapers and magazines to be sold outside newsagents.

"We're being swallowed up by multinationals," he said.
