The state government has expanded the criteria for venues that are allowed to open for indoor dining, effective immediately.

As of today, any venue with a seated dining area can open for up to 10 patrons (and another 10 outside), premier Steven Marshall announced in a press conference this afternoon.

The new ruling overwrites changes announced earlier this week that would allow cafes and restaurants (only) to open for indoor dining today and comes after major confusion over what actually constitutes a restaurant.

"We have created some confusion in South Australia around indoor dining," Marshall said. "Diners don't really know what licence an individual establishment has."

Under the previous restrictions, venues such as Leigh Street Wine Room, 2KW and Peel St – which operate under a small venue licence rather than a restaurant and catering licence – couldn't open. The same goes for Osteria Oggi, which had reopened today before swiftly being instructed to shut its doors.

The changes will now allow these venues and other licensed premises such as pubs, bars and wineries to re-open, as long as they have dining capabilities.

Venues will still be required to adhere to social distancing guidelines of one person per four square metres.

More to come.
