Logoghu, Qantas ended up buying the ex BA 767s outright. It was cheaper than returning them to their original config for return to BA at the end of the lease.
Some of them ended up with a cargo mob. Various destinations for them included Roswell, Kansas City, Victorville and I think one went to Shangai for a service before heading to Japan where it's flogging around domestically for someone.
Apparently the 767-338s are worth more on the open market than the 744s Qantas are disposing of.
