The Retail and Commercial Leases Act 1995 makes void any provision of a commercial tenancy agreement 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 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 is unlawful for the tenant to trade
Shops in the Greater Adelaide Shopping District (central shopping district, the Glenelg tourist precinct and the metropolitan area) are not required to open on a Sunday even if required by a retail shop lease or other determination.
