Airlines have a choice of method -from
Australian Government - Residual - is carried out while no passengers are onboard. The entire aircraft is sprayed with a residual insecticide and lasts eight weeks
- Pre-embarkation - is carried out while no passengers are on board. Crew may be on board as this method is completed up to 40 minutes prior to passengers boarding the aircraft. The treatment lasts for the duration of the single flight
- Pre-flight and top of descent - refers to a two-part process consisting of pre-flight and top of descent spraying. Pre-flight spraying is followed by a further in-flight spray of a non-residual insecticide, carried out at top of descent as the aircraft starts its descent into either Australia or New Zealand. The treatment lasts for the duration of the single flight
- On-arrival - is an in-flight spray of a non- residual insecticide, carried out once the aircraft lands in Australia or New Zealand. The treatment lasts for that one arrival.
ALL planes have to be sprayed at some point. There is no exemption for QF and it is nonsense to say that there is.
