If the incoming National-Act government is concerned about the exodus to Australia, here’s a quick solution.
Lock anyone with a one-way ticket to Australia in a small room, their hands handcuffed behind their back to prevent them covering their ears.
Then subject them to a 5 minute recording of Prime Minister Anthony Albanese talking. After 2 minutes they’ll be screaming for mercy and when released, clog the Airline desk to cancel their flight.
