Any ideas what is happening to this aircraft. A review of the last couple of weeks show it off the regular schedule and visiting some interesting locations. Not sure if it is a charter or if the aircraft has been sold. Planespotters.net still show it as a QF aircraft and their data is generally excellent.
Ideas?

It must be a stealth. I can’t see it.

Apologies. VH-OEB is the aircraft of interest.
