The Australian Retailers Association urged states and territories to quickly clarify trading conditions for the one-off holiday which falls next Thursday, on September 22.
“This event will create some complications for businesses with store closures and staff scheduling challenges,” ARA boss Paul Zahra said.
Many work rosters were set up weeks in advance, he said.
“There will also be a small but unexpected loss of trade, and additional staffing costs, which may impact cashflows for small businesses.”
He was “confident” retailers will “abide respectfully” by the government’s decision.
The public holiday will be a one-off to allow Australians to pay their respects.
