From memory, the 2 x DC9s were finally operated by Australasian Jet (??), who also operated a B727 200F based in Perth.
The DC9s were puchased by Evergreen International which purchased them from the leasor/owner. Again from memory Australian Jet wanted to keep them.
It was a while ago and I no longer have the records but that is the way I remember it.
