An illicit tobacco expert says it's clear the trade has established a foothold here.

The Government has already created an action group of Customs, police, and health officials - with improved planning and joint operations to fight the illegal trade.

Former Australian detective Rohan Pike says he's already managed to buy an illegal pack.

"It took me about one minute after landing on Sunday night to find these at a convenience store straight across the road from my hotel."
