Drug dealers are increasingly sending drugs through the mail, Victorian police say.
Detective Superintendent Craig Darlow says police and partner agencies have been cracking down on international and domestic mail since December.
"We're seeing an increase in drugs in the mail," Det Supt Darlow told 3AW on Friday.
Victoria Police has been working with Australian Border Force, Australian Federal Police, the Department of Home Affairs and Australia Post on the blitz.
"We go out to the Melbourne gateway facility and target specific items of mail," Det Supt Darlow said.
"What we're seeing is not real good at this stage.
"We know there's various types of drugs being moved through the mail system, both national and international, and our seizures ... have been quite significant."
A French tourist was deported last month after being charged with posting heroin to his backpacker's accommodation ahead of the Rainbow Serpent Festival in rural Victoria, the Herald Sun reports.
Det Supt Darlow said the tourist was charged on two separate occasions for separate importations.
