Singapore Airlines will be the first carrier to resume flights to and from Adelaide Airport from next week.

The airline will begin reinstating a weekly flight between Adelaide and Singapore, the first regular international flights since late March.

Travel restrictions both in and out of Australia and South Australia, however, remain in tact.

Aussies seeking to leave Australia will still be required to seek an exemption from the Department of Home Affairs, while those arriving are required to quarantine on arrival.

The first of the weekly flights will arrive from Singapore next Tuesday morning at 7:55am, before departing at 9:10am.

The news comes as Premier Steven Marshall flags July 3 as a possible date to begin easing travel restrictions into and out of South Australia.

SA is reportedly exploring a “travel bubble” with Tasmania, however concerns remain about reinstating travel between SA and Canberra with no travel restrictions for those entering the nation’s capital from New South Wales or Victoria.
