Senior police officers said they were surprised and shocked at the large number of firearms found during the joint operation with the Australian Border Force.
In total, 18 imitation firearms and 75 firearm parts were seized, 35 people were arrested and 189 charges were laid last week.
Detective Superintendent Jason Kelly said the trafficking and use of illicit firearms remained a key law enforcement issue across Australia.
“Firearms-related violence is one of the most significant issues we face, and we understand there is immense community concern when it comes to these weapons,” he said.
“As we know, illicit firearms have traditionally been used in a range of violent crimes such as murder, shootings causing serious injuries, armed robbery, threats to kill, and extortion.”
