There is still a grey area with para-drops that has been debated and im sill unsure about so correct me if I am wrong. A display team is jumping into the local footy game and there isn't a DZ/jump aircraft available close to the location...
Sections 3 of the Instrument number CASA 405/09 defines a Jump Aircraft as
jump aircraft means any aircraft engaged in the dropping of parachutists in parachute training operations.
So assuming your theoretical display team are not carrying Tandem students, the pilot does not have hold an APF authorisation.
