The Royal Brunei Navy and the Australian Defence Force have commenced Exercise Penguin 25, the leading bilateral maritime security activity between the two countries.

“Australia and Brunei Darussalam’s long-standing defence relationship dates back to World War II, and is underpinned by strong people-to-people links and a shared interest in a stable, secure, and prosperous region,” First Admiral Sahibul Bahari said.
“We look forward to hosting the event and for members of the Royal Brunei Navy to train alongside the Royal Australian Navy to increase our capacity to support each other in the Indo-Pacific region.”

“This year will be the 20th iteration of Exercise Penguin, further reinforcing the depth and growing collaboration between our defence forces,” Vice Admiral Hammond said.
