The targeted entities include Iran's Islamic Revolutionary Guard Corps (IRGC) navy, which seized an Israeli-linked, Portuguese-flagged, civilian ship in international waters on April 13.

Australian Foreign Minister Penny Wong said, "Australia is demanding the immediate release of the ship and its crew."

There are also 16 Indian crew members on board the seized container ship MSC Aries.

The senior officials sanctioned by Australia on Tuesday include Iran's Defense Minister Mohammad Reza Ashtiani and IRGC Quds Force commander Brigadier General Esmail Qani.

"The IRGC is a lethal actor that has long been a threat to international security and its own people," Wong said in a statement released by the Australian government.

Those sanctioned also include senior Iranian officials, business people and companies that have contributed to the development of Iran's missile and unmanned aerial vehicle (UAV) programs.

"Iran's proliferation and provision of these technologies to its proxies has fueled instability throughout the region for many years," Wong said.

The Australian government, led by Prime Minister Anthony Albanese, has not imposed any sanctions on 90 individuals and 100 Iran-linked entities.

“This action is consistent with the sanctions measures taken by our partners in recent weeks following Iran's unprecedented drone and missile attack on Israel in April. Australia deliberately and strategically calls on Iran to stop its disruptive activities and comply with international law. , Wong said.
