Occupancy rates have increased with a steady growth in tourism across the state.
The latest data from Tourism Research Australia reported a 57 per cent increase in regional spend compared to pre-covid.
Tourism minister Zoe Bettison said tourism in regional SA had been performing well, driven by locals exploring their own backyard and strength in the international market.
"The amazing weather we had over the Easter break this year saw more people out and about, with increased visitation to seaside towns such as Robe," she said.
"Data shows some regions are experiencing record high visitor spend, such as the Clare Valley and Murray River, Lakes & Coorong.
"It has been great to see visitors explore our state's Murray River regions and support operators who were hit hard by the once-in-a-century flooding event in 2022/23."
Visitor spend in the Riverland and Murray River, Lakes & Coorong regions had a combined increase of $171 million since the impacts of the flood.
In the Mid North, The Park owner Ali Cooper, Jamestown, said tourism was booming as their occupancy rates continued to climb year on year.
"We run at a very high occupancy rate in all of our cabins and villas and then we have a peak time for powered site occupancies, and generally it's from March through to October," she said.
"But this year until now, we've been running at a higher occupancy rate than last year, which was higher than the previous year as well.
"Our cabins and villas have an occupancy rate of about 85pc which in the accommodation industry is fairly high - hotels in Adelaide run at about 60pc."
She said they felt like they turn more people away than they say they have availability but visitors were basing themselves at Jamestown to go on day trips within the region.
In the South East at Echo Farm Tours owner Anthea Harrison, Mount Gambier, said their seven hectare working farm was open to the public for walk-ins.
"We get out of school hours care school groups come through and we do an education program allowing people to see the animals in their natural environment," she said.
"Tourism has been pretty good during the school holidays because there has been a month of school holidays between Victoria and SA.
"We don't get so much the touring family but more the international tourists."
While over on the Eyre Peninsula, Australian Coastal Safaris owner David Doudle, Port Lincoln, said about 80pc of their business were international tourists and then interstate travellers.
"I think for the amount of bookings we have for the rest of the year and into next year, tourism is looking very positive," he said.
He said their tours were a specialised product tailored to their customers' wants.
"Our mountain bike hire is probably the attraction to the local market and they're usually booked during school holidays," he said.
"We probably have a similar amount of people coming through now as we did 12 months ago.
"But we do get to a point where we can't take any more people on tours because we haven't got the availability of vehicles."
