A warning drug traffickers are crafty - and will change their methods at the drop of a hat

Customs has repositioned staff at airports - after re-deploying many of them because of an absence of passengers.

Police report border closures disrupted the drug trade... but New Zealand's now opened back up to Australia.

Customs Manager Bruce Berry says where there's a possible supply chain - criminals will try to exploit it.

He says they need to show agility in their response across agencies - with domestic and international partners.
