Councillors at Robe have unanimously backed new coronavirus restrictions at popular tourist spots.
Robe District Council has told of closures of the town's boat ramp, Long Beach and Ski Lake boat ramp.
The closures will apply from 6am on Thursday, April 9, until 6pm on Wednesday, April 15.
By restricting tourists and residents, the council hopes to minimise any spread of the deadly disease.
This comes after the council last month discouraged people from visiting Robe amid the COVID-19 scare.
In outlining the latest action, Mayor Alison Nunan said on Saturday the safety of residents, both ratepayers and guests, was of "utmost concern".
"Our objective is to look after the health and well-being of the people in the council area and, consequently, our state," she said.
"Our Prime Minister has stressed that holiday travel is considered non-essential and he has told people to cancel all non-essential travel.
"This is echoed by the Premier.
"As directed by government and our health professionals, social distancing and non-essential travel guidelines need to be followed to stop the spread of the virus around the country and in South Australia.
"We all know that we are in trying and uncharted times.
"Our council will continue to make strong, considered decisions for the health of our wider community.
"I wish to thank everyone for the support we have received as we have worked through this difficult time.
"Please respect and understand our decisions and don't travel to Robe at this time unless it is essential."
