Raids were undertaken at properties in Bellfield and Thomastown in Melbourne’s north on Thursday and several people were spoken to by police.
Enquiries are continuing and charges have not been ruled out, police said.
Federal Police acting Commander of Investigations Jayne Crossling said the seizure demonstrated how drug smuggling was continuing throughout the pandemic.
“COVID-19 has not stopped drug dealers or organised crime syndicates from trying to import illicit products into Australia,” she said.
“Drugs and drug abuse have severe consequences for the Australian community.
“Those with illicit substances in their system are unpredictable and it’s not just their health they are putting at risk, but those around them.”
Border Force Regional Commander for Victoria and Tasmania, Craig Palmer, said the detection showed criminals will go to “creative lengths” to sneak illegal drugs into the country.
“Despite their attempts, criminal concealments are no match for our officers who are well-trained to detect such efforts,” he said.
Anyone with information that may assist investigators is urged to contact Crime Stoppers on 1800 333 000.
