The Royal Australian Navy hydrographic survey ship HMAS Leeuwin has docked in Lae, Papua New Guinea, to commence a month-long mission focused on charting the nation's waters.

The operation aims to enhance maritime safety by updating nautical data while simultaneously strengthening defence ties between Australia and Papua New Guinea.

The deployment underscores the strategic importance of accurate hydrographic data in the region, where complex coastlines and limited historical survey coverage can pose risks to commercial shipping and naval operations.

Improved mapping supports safer navigation for vessels transiting through key Pacific routes, which remain vital for regional trade and energy exports.

This mission aligns with broader efforts by Australia to deepen security cooperation with Pacific Island nations.

The presence of the HMAS Leeuwin serves as a tangible demonstration of commitment to regional stability and maritime domain awareness, areas of increasing focus amid evolving geopolitical dynamics in the Indo-Pacific.
