Heroin and ice along with designer goods valued at $200,000 were allegedly found in raids at Melbourne properties with a trio accused of using the mail to traffic drugs.

A 35-year-old man and a 32-year-old woman were arrested after raids at a Southbank property on Friday while a 28-year-old man was also arrested in Port Melbourne.

Officers from Joint Task Force Icarus specifically targeted people using the dark web and crypto-currencies for drug transactions using Australia's domestic mail system, Detective Acting Superintendent Craig Darlow said.

At the Southbank property, officers allegedly found large amounts of ice, heroin ecstasy and cocaine along with designer shoes, handbags, purses and watches valued at around $200,000.

In Port Melbourne, officers allegedly uncovered the quantities of ice and a large amount of cash.

The woman and two men have been charged with various offences including trafficking a commercial quantity of drugs and possessing proceeds of crime.

The group appeared in the Melbourne Magistrates Court on Saturday morning.
