Cafes and restaurants will be able to seat up to 20 people come Friday with pubs across South Australia being allowed to open on June 5 as the State Government eases more restrictions on hospitality.
From Friday, May 20, restaurants and cafes will be able seat 10 patrons inside and 10 patrons outside the premises if safe distancing procedures allow.
Alcohol will also be allowed to be served to diners on the premises.
Premier Steven Marshall said that from June 5 South Australian pubs can open, allowing businesses a much-needed economic and morale boost ahead of the long weekend.
"This is all about accelerating local economic and jobs recovery, while rewarding South Australians for their outstanding efforts over many weeks in helping stop the spread of this virus," Mr Marshall said.
"And now, by bringing forward the ability for restaurants and cafes to offer indoor dining and serve alcoholic beverages to Friday, we will further support our hospitality sector as it recovers from the greatest economic challenge of our time.
"Hotels can also look forward to opening earlier than scheduled to capitalise on the entire June long weekend, which will bring a further economic and morale boost for South Australians."
Across the coming days there will be safeguards put in place by the State Government which must be adhered to by hospitality businesses and the general public.
Business SA chief executive Martin Haese said it was another positive step for the state's business owners.
"We thoroughly commend the Premier for listening to input from Business SA and the broader business community to bring forward the start date for Stage 2 restrictions from the Queen's Birthday public holiday on Monday 8 June back to Friday 5 June," Mr Haese said.
"However, Business SA knows there are still much bigger issues at play, particularly around the four-square metre rule which will restrict venues to operate at 25 per cent capacity.
"Bringing forward the start date for Stage 2 will however, provide businesses with some clarity that regardless of how many people they are allowed inside their venue, they can at least open their doors for the full long weekend.
"This is also a win for our regions and should encourage more intrastate travel over the long weekend, which will benefit businesses in some of our smaller towns."
Minister for Health and Wellbeing Stephen Wade said that because South Australians were still testing in increasing numbers and with no new cases.
"Whilst the return of indoor dining and the option of having a drink with your meal is a welcome step towards normality, we must not become complacent about the ongoing need to protect ourselves and each other from COVID-19.
"Cafes and restaurants will need to follow strict hygiene procedures when reopening.
"I urge all South Australians to continue to practice the personal health measures that have bought us so much success in controlling COVID-19."
