Southeast Asian powerhouse Singapore Airlines, is ramping up its services into Australia over the next two months. In terms of passenger numbers, Singapore Airlines is usually the third biggest carrier in and out of Australia, with over 140 weekly flights to various airports. But in March, Singapore Airlines cut flights to virtually all its destinations. However, Australia is back on the radar with flights set to resume to Sydney, Melbourne, Brisbane, and Adelaide.

It's not exactly the lavish schedule it once was. Still, with Singapore gradually re-opening its borders to transit passengers, the airline is tentatively re-opening some routes with slimmed-down schedules.

Escaping the Melbourne chill

Melbourne is back in the timetable with two return services a week across June and July. There will be late evening departures out of Singapore and down to Melbourne on June 8, 15, 22, and 29, and July 6, 13, 20, and 27. If you prefer a daytime flight, there will be departures from Singapore late morning on June 12, 19, and 26, and July 3, 10, 17, 24, and 31.

If you're keen to escape the Melbourne winter, Singapore Airlines will be flying out of Melbourne on June 9, 16, 23, and 30, and July 7, 14, 21, 28. These are late evening departures. Also, there will be mid-morning departures on June 13, 20, and 27, and July 4, 11, 18, and 25.

A little love for Adelaide

A little further west, Adelaide is also getting a little Singapore Airlines love with a weekly return flight. Flights out of Singapore will depart late evening on June 8, 15, 22, and 29, and July 6, 13, 20, and 27. The return flights will leave Adelaide mid-morning on June 9, 16, 23, and 30, and July 7, 14, 21, and 28. Too bad Adelaide has just permanently closed its KrisFlyer lounge.

Things are busier in Sydney

Things are a little busier at Sydney with five flights a week, although it's still a step back from the four daily Singapore Airlines flights the airport hosted until recently. Out of Singapore, there will be mid-morning departures on June 2, 5, 7, 9, 12, 16, 19, 23, 26, and 30, and July 3, 7, 10, 14, 17, 21, 24, 28, and 31. In addition, there will be midnight departures from Singapore on June 8, 10, 14, 15, 17, 21, 22, 24, 28, and 29, and July 1, 5, 6, 8, 12, 13, 15, 19, 20, 22, 26, 27, and 29.

If you need to exit Sydney, Singapore Airlines has midday departures listed for June 1, 3, 6, 8, 19, 11, 15, 16, 18, 22, 23, 25, 29, 30, and July 2, 6, 7, 9, 13, 14, 16, 20, 21, 23, 27, 28, and 30.

There are also additional flights out of Sydney going via Brisbane. These are mid-evening departures on June 9, 12, 16, 19, 23, 26, and 30, and July 3, 7, 10, 14, 17, 21, 24, 28 and 31.

Twice-weekly services into Brisbane

Brisbane will be hosting two Singapore Airlines services per week across June and July. The down flight, out of Singapore, is operating via Sydney. Departures from Singapore are on June 9, 12, 16, 19, 23, 26, and 30, and July 3, 7, 10, 14, 17, 21, 24, 28, and 31. These are daytime flights. The Sydney - Brisbane sector would be a nice little run on Singapore Airlines if Australia allowed the airline domestic cabotage, and Queensland was letting any outsiders in.

The leg between Brisbane and Singapore is a direct overnight flight with departures on June 9, 12, 16, 19, 23, 26, and 30, and July July 3, 7, 10, 14, 17, 21, 24, 28, and 31.

Services to New Zealand, nothing to Perth, Darwin or Cairns

All Singapore Airlines' Australian services will use an A350-900. That's a step up from some of the aircraft that service the many Singapore Airlines flights usually flying into Australia. It could also be a step down if you're a fan of the Singapore Airlines A380s that frequent Melbourne and Sydney.

The biggest loser in this expansion is Perth, which usually hosts up to five Singapore Airlines services a day. There is no imminent return of Silkair services to Darwin or Cairns.

Note that Singapore remains closed to non-nationals and is only allowing carefully controlled transit traffic. Australia also remains shut to non-nationals.

In addition to these increased services into Australia, New Zealand is back on Singapore Airlines' radar with weekly flights into Christchurch and twice-weekly flights into Auckland re-starting.
