Is that a Russian Antonov AN-124 sitting at Canberra airport?
It has Russian colours on the tail.
If it is then it is the largest plane to land there and is used to transport the Erickson skycrane. – these are being assembled by going past the old Fairbairn air force base and just past the current airforce hangers.
The AN-124 can carry a payload of 230 tonnes. Approx 100 of these aircraft were built and are the largest commercially operated aircraft in the world. They are 30% larger than a C5 galaxy.
If they bring these freighters in at night it will be just like back home on the Mornington Peninsula and listening to the freighter (probably an old jumbo) going overhead at 3:00 am to Avalon.
[Ed – They have just completed the air-strip improvements and are very excited about being able to take heavier freight (shame about lacking a railhead or decent road links)]
