SEVEN-day trading could hit Dalby's small business community hard, according to Foodworks general manager Nicole Simpson.
Ms Simpson said the store had been trading on Sundays since it moved to Condamine St.
"It was a business decision. We don't have a lot of competitive edge against the chains," she said.
"It was the only thing for us to stay afloat. It still helps us to stay afloat."
The National Retailers Association has applied to extend Dalby trading to Sunday and public holidays.
Woolworths, Coles and any national chain store would remain open all week if the application was approved.
Ms Simpson said having larger supermarkets open on a Sunday would be "extremely detrimental".
"Sunday is quite a big part of our trade," she said.
A previous application for seven-day trading was declined in 2010.
Dalby Shoppingworld manager Jon Russell said he welcomed seven-day trading.
"It's keeping money in the town," Mr Russell said.
He said whether or not businesses within the centre opened on the day was their decision.
"I believe a lot of the businesses will try it. You can't blame them for that," Mr Russell said.
Dalby Chamber of Commerce will host an information evening to discuss the application and how the community can make submissions next Tuesday from 6pm.
Manager Peter Brown said the chamber's role was to inform the community about the application.
"We believe that our responsibility is to make people aware of what the process is," Mr Brown said.
An Industrial Relations Commission hearing of evidence is scheduled in Dalby for November 17-19.
Applications for evidence at the hearing close on September 26.
