South Australia reported its first new cases of coronavirus in a month with three infections detected among Australians who returned from India by plane this weekend.
SA Health says a three-year-old girl and two women tested positive after flying from Mumbai on Saturday.
Chief Public Health Officer Nicola Spurrier says the cases are not a surprise given the high rate of infections on the subcontinent.

A plan for South Australia to lift border restrictions with Victoria is also “under a cloud” amid the continuing spike in coronavirus cases in Melbourne, said Prime Minister Steven Marshall.
Mr. Marshall stressed that SA will not lift the quarantine requirements for anyone arriving from Victoria if it is not safe to do so.
Under the current arrangements, SA is expected to lift these measures on July 20.
“So we still have three weeks, but it is now under a cloud,” the Prime Minister said on Monday.
“We will look into this very closely and inform the people of South Australia as soon as possible.
“We are very concerned about the numbers coming out of Victoria right now, there is no question.”
Victoria reported 75 cases of coronavirus today after revealing 90 new infections over the weekend.
Police Commissioner Grant Stevens said he would seek advice from SA Health experts regarding efforts in Victoria to contain the virus and properly establish the extent of the spread in the Victorian community.
“The reality is that the numbers we see today are related to activities that have taken place in the past two weeks, so we can see a much better performance from Victoria over the next few days,” said Stevens .
“It is important to everyone that Victoria masters all of this.”
As of Wednesday, SA is also moving to a pre-approval system for everyone entering the state under the current COVID-19 restrictions.
Anyone wishing to travel to South Africa by road or by plane will have to apply via an online form, according to a process that will speed up access to state borders.
People arriving from Queensland, Western Australia, Tasmania and the Northern Territory will not be required to quarantine, but 14 days of isolation will continue for anyone from New South Wales, Victoria and ACT.
SA did not report any new cases of coronavirus on Sunday, bringing the delay from several days without new infection to more than a month.
However, 250 Australian returnees arrived in Adelaide from India on Saturday and local health officials have warned that this could lead to new cases.
