After being de-registered in early June, and sitting idle at Sydney Airport with all red tails and their titles removed, they finally departed Australia this week on (presumably) their long journey to Canada where they are now registered.
Both aircraft are registered to the Avmax Group (Canada), who appear to be an aircraft leasing company. There is speculation (unfortunately) that they could be scrapped.
I hope not! I have very fond memories of flying on VH-SDA and VH-SDE most holidays!
