It happens to every airline/flight entering Australia. Some airlines like QF/NZ do residual spraying if their aircraft operate here frequently as it has to be done regularly. UA does residual spraying of their 744s - it used to be done on the ground in SYD.

Other airlines (like CX from HKG as example) spray the aircraft before boarding and present the used spray cans to Quarantine on arrival.

Airlines based in Nth America still spraying on arrival include HA and AC because the spray cannot be used in Nth America. I heard that DL was going to residual spray in Asia during long ground times but that plan may have changed.

Bottom line = ALL aircraft to Aust are still sprayed.

Another Delta overnight
 

I was driving along Qantas Drive and saw another Delta 777 in the QF parking lot. So do we know if this is due to the spraying issues? If so, how are they doing this now?

That's interesting re Nth America as one of the questions they ask on the USA paperwork inb is for the expiry date of the residual spray on the aircraft.

FYI the process I've seen for an expired residual or no residual is normally to spray at TOD inbound to the required destination or at the required destination under the supervision of the local authorities.
