Shopping hours in South Australia are still regulated, but there have been numerous changes to relax the laws. Nonetheless, trading laws are still face complicated and confusing: legal trading hours vary depending on size and product offer. Supermarkets that trade with fewer than seven workers and with a trading floor less than 500 m2 are exempt from the laws. Larger supermarkets are required by law to close at 9 pm on Mondays to Fridays, and 5 pm on Saturdays; they are permitted to trade on Sundays and public holidays only from 11am to 5pm, except ANZAC Day, which is 12 noon to 5pm; they must remain closed on Good Friday, Easter Sunday and Christmas Day.
