Holiday inside SA, locals urged

South Australians are being urged to roam their state to help communities and businesses that have suffered from coronavirus restrictions, which came after drought and fires in some regions.

Premier Steven Marshall said the $1.5 million 'Welcome Back' tourism campaign launched on Sunday was about getting tourism regions back on their feet as quickly as possible.

Since intrastate restrictions were eased on May 8, regions had reported huge amounts of web traffic and phone calls, with places in the Riverland, Yorke Peninsula, Barossa and Flinders Ranges already booked out for the June long weekend, Mr Marshall said.

The campaign is similar to the successful #BookThemOut campaign to help Kangaroo Island and the Adelaide Hills recover from devastating summer bushfires, and also urges South Australians to explore Adelaide.

"We have heard directly from accommodation providers that people are coming back," Mr Marshall said.

"New data from Airbnb has shown a surge in domestic bookings, particularly in regional areas, with South Australia reporting a significant increase in same-state travel, with bookings up 77 per cent compared with the same week last year."

The state border remains closed.
