ROYAL Australian Navy (RAN) hydrographic survey ship HMAS Leeuwin has arrived in Lae for a port visit as part of its regional hydrographic survey mission in support of the Government of Papua New Guinea (PNG).
The deployment, running from 13 July to 16 August 2026, is collecting hydrographic data that will contribute to the development of updated nautical charts and improve the safety of navigation in PNG waters.
During the mission, HMAS Leeuwin is providing mentoring and practical training opportunities for embarked membersof the Papua New Guinea Defence Force (PNGDF), strengthening maritime capability and reinforcing the longstanding partnership between Australia and PNG.
While in Lae, the ship will have the opportunity to experience the hospitality and culture of Morobe Province and engage with members of the local community before returning to sea to continue survey operations around Umboi Island.

HMAS Leeuwin is the lead ship of the RAN’s Leeuwin-class hydrographic survey vessels. The RAN Hydrographic Service is responsible for charting more than one-eighth of the world’s surface, covering an area that extends from Cocos (Keeling) Islands in the Indian Ocean to the Solomon Islands, and from the Equator to Antarctica.
The survey mission will support the creation of updated nautical charts, helping make travel by sea safer for communities, government vessels and commercial operators across Papua New Guinea.
The deployment highlights the strong and enduring defence partnership between Australia and Papua New Guinea and a shared commitment to maritime safety, security and regional cooperation. The mission reflects the practical cooperation envisaged under the PNG–Australia Pukpuk Treaty and demonstrates the close relationship between the two nations.
