Defence Minister Marise Payne is heading to South Korea as tensions in the region reach fever pitch following Pyongyang's latest nuclear weapon test.
Senator Payne will leave on Wednesday to meet with the South Korean prime minister and defence minister, and deliver a speech at a forum on regional and global security.
"We strongly support South Korea and the United States as they work to address the challenges of North Korea," the minister told parliament on Monday.
Senator Payne spoke with her Japanese counterpart on Monday morning to discuss the North Korean threat, following the latest nuclear test and a ballistic missile launch last week.
"Australia and Japan have both unequivocally condemned the illegal tests and call further upon all nations to implement the UN sanctions against North Korea," she said.
The minister will also travel to the Philippines after her visit to Korea to discuss an Islamist uprising in Marawi.
