When HMAS Supply passed Horsburgh Lighthouse on July 6, it was more than another navigation waypoint for the ship’s first lieutenant, Lieutenant Luke Horsburgh.
The active lighthouse, which marks the eastern entrance to the Straits of Singapore, shares the same surname as the maritime combat officer and has become a familiar landmark throughout his naval career.
For Lieutenant Horsburgh, seeing his family name displayed on charts and navigational references has always added an extra layer of significance to each transit.
He joined the Royal Australian Navy on May 8, 2006, as a boatswain’s mate before commissioning as a maritime combat officer on July 4, 2025.
The 2026 passage during Supply’s regional presence deployment prompted reflection on the first time he sailed past the lighthouse about two decades earlier.
“My first time past Horsburgh Lighthouse was around 2007 on the mighty battle tanker HMAS Success,” Lieutenant Horsburgh said.
“At the time I was a junior sailor, and I never imagined I’d one day be passing it again as a lieutenant.”
He has transited past Horsburgh Lighthouse on multiple occasions throughout his career, but the latest passage highlighted the professional journey from enlisted sailor to commissioned officer.
For Lieutenant Horsburgh, the familiar landmark represents more than a point on the chart. It serves as a reminder of two decades of service, professional growth and the experiences gained at sea.
