A man has been arrested in Sydney for allegedly acting as an economic agent for North Korea, Australian Federal Police (AFP) have said.
Chan Han Choi, 59, has been charged with brokering illegal exports from the country and discussing the supply of weapons of mass destruction.
Police allege he has broken both UN and Australian sanctions.
The case against Mr Chan, who has lived in Australia for more than 30 years, is the first of its kind in the country.
It is the first time anyone has been charged under the country's 1995 Weapons of Mass Destruction (Prevention of Proliferation) Act.
Police say there was evidence that Mr Chan had been in contact with "high ranking officials in North Korea".
They allege he had brokered services related to North Korea's weapons programme, including the sale of specialist services including ballistic missile technology to foreign entities, in order to generate income for the North Korean regime.
Mr Chan also was charged with brokering the sale of coal from North Korea to groups in Indonesia and Vietnam. He is facing six charges in total after being arrested at his home on Saturday night.
Mr Chan could face up to 10 years in prison and has been denied bail, reports BBC.
