The Retail and Commercial Leases Act 1995 voids any commercial tenancy agreement provision which requires a tenant to:
- open for business outside core trading hours of the shopping complex or standard trading hours
- core hours cannot exceed 54 per week nor include anytime on a Sunday
- pay for costs of the complex incurred outside core trading hours when the tenant's shop was not open for business or when it's unlawful to trade.
Shops in the Greater Adelaide Shopping District (central business district tourist precinct, the Glenelg tourist precinct and the metropolitan area) are not obliged to open on a Sunday, even if required by a retail shop lease or other determination.
