Police in the ACT have seized drugs worth $3 million as part of a nationwide crackdown on organised crime and people who traffic narcotics through the postal system.
A gun and hundreds of bullets were also found in Gunghalin in the week-long operation.
Officers in Canberra also retrieved half a million dollars in cash as part of Operation Vitreus which was set up in 2017 when the authorities realised that Australia Post was a favoured medium for drug traffickers.
ACT Policing said they did 15 raids on suspect premises across Canberra last week.
In those raids, officers seized more than 1000 cannabis plants and more than 42 kilos of dried cannabis.
About 280 grams of cocaine were also found.
In addition to the $3 million of drugs in the ACT, NSW Police said they seized more $14 million of drugs during the Operation Vitreus actions.
In the Canberra raids, officers said they also found illegal fireworks, steroids and a prohibited knife.
On Thursday, two men were arrested following a search warrant at a property in Flynn. Both have been charged with growing and distributing cannabis.
Operation Vitreus is a joint operation involving forces in all the states and territories plus New Zealand police and the Australian Border Force. The Australian Tax Office is also part of the operation.
When it was set up, the Australian Criminal Intelligence Commission which coordinates it said: "With tens of thousands of mail items scanned throughout the country at state and international mail exchanges over two days, authorities located an alarming array of illicit substances.
"The largest seizures were of methylamphetamine, cannabis, and cocaine however a total of 62 illicit drugs or illegally obtained prescription medications were seized by police."
The operation has since broadened to include organised crime and drug supply in general.
On last week's ACT operation, detective acting Inspector Dale Ohlmus said that he was pleased with the way the national coordination and sharing of information had gone.
"Working with our state and territory partners allows us to share information about local drug trafficking networks, giving us valuable information to help identify and dismantle these groups.
"Illicit drugs cause harm to our community, whether that be watching a loved one struggle with addiction to being the victim of drug-related property crime, or a collision with a drug-affected driver.
"That's why we're targeting those who seek to profit from the harm caused by illicit drugs.
"Anyone with information about the sale and supply of illicit drugs should contact Crime Stoppers on 1800 333 000 or via the Crime Stoppers ACT website. Information can be provided anonymously."
Since October last year, using relatively small amounts of drugs in the ACT has been an offence but not technically a crime (like speeding or driving offences). Trading and/or making drugs remains a punishable crime.
