I'd be interested to see if Croydon Travel are looking for a new operator or if they are giving it away. Both Croydon and Qantas do very well out of these flights.
I believe there are 5 planned this upcoming season; a combination of Sydney, Brisbane, Melbourne, Adelaide and Perth departures.
Having flown a few of these trips I can highly recommend the day out. New Year trip is quite a party and almost continuous daylight despite arriving over the ice after 10:00pm and the scenery on the other trips -over the ice in the middle of the day- is usually stunning. The mountainous area around Cape Hallett is probably the best viewing but all the coastline west from there is unique and a few laps over Casey always has the pax intrigued about the isolation of the place.
