The Retail Traders' Association says the success of the first day of Sunday trading at Joondalup has sent a clear message to the state government that people want shopping hours to be more flexible.
Thousands of people went to Joondalup yesterday, to take advantage of the shops being open.
"Demand for the choice to be able to shop on Sundays was so great that crowds queued outside stores waiting for them to open," said RTA director Wayne Spencer.
Mr Spencer said the state's retail trading laws are archaic and needed updating.
"The State Government knows it's on a winner with the public, with the Minister for Commerce Bill Marmion saying the big turnout vindicated the government's approach to changing Perth's archaic shopping rules," he said.
"Yet, the Government is only prepared to allow shops in Joondalup, Midland, Armadale, Perth and Fremantle to trade on Sundays.
"This is unfair to the many retailers and shoppers who live outside these areas and would like to enjoy the same level of choice and competition."
Mr Spencer said the success of Joondalup's first day of Sunday trading reflects independent polling which shows that 7 out of 10 Perth people want to be able to shop on Sundays and weeknights.
