A number of repatriated Aussies have arrived in Adelaide on the first regular international flight into Adelaide for months.

The flight from Singapore was the first of the reinstated Singapore Airlines service which will fly weekly between the two cities.

Passengers who arrived on this morning’s flight will have to complete mandatory 14-day supervised isolation.

The flight arrived in Adelaide just before 8am this morning before leaving for Singapore just after 9am.

While international travel restrictions remain for Australia, South Australia has announced that its borders will open for interstate travel next month.
