Permanent Sunday trading has been welcomed by the Rockingham Kwinana Chamber of Commerce and Rockingham Shopping Centre.
The State Government announced all shops in the Perth metropolitan area could open their doors on Sundays, starting on August 26, after amendments to the Retail Trading Hours Act passed through Parliament last month.
The new laws enable shops to trade from 11am to 5pm on Sundays.
Rockingham Shopping Centre manager David Murray said the new legislation would remove the confusion about which Sundays the centre opened.
The centre operates under the Retail Trading Hours (Rockingham Holiday Resort) Order 2010, which means it can only open on Sundays during school holidays and public holiday weekends.
Mr Murray said a recent survey conducted by the centre revealed more than 80 per cent of respondents were in favour of Sunday trading.
He said the centre would carry out a marketing campaign to promote the new trading hours.
Chamber vice-president John Cotter said regular Sunday trading in Rockingham was positive news and would hopefully attract more visitors to the city.
Rockingham Shopping Centre store Matchbox will open every Sunday when the new trading hours come into effect, according to manager Denise Ciraulo.
She said she would have to wait and see if regular Sunday trading was popular with customers.
