After months of chasing I finally got her. This is one of two Bluebird Cargo's 737 with a white livery (normally it is blue).
Newest addition in the Bluebird Cargo fleet is this ex Qantas 737-400 (VH-TJK). Converted to cargo in 2014 by Airwork and now leased by Bluebird Cargo as from March 25th.
...'BBD291' for 31L...
