In the dynamic workplace of an Australian warship at sea, Leading Seaman (LS) Communication Information Systems Matthew Tymrakiewicz is a gatekeeper of HMAS Darwin's essential links with the outside world.
Darwin is currently deployed on Operation Manitou, which is the Australian Defence Force contribution to support international efforts in promoting maritime security, stability and prosperity in the Middle East region.
The objective of Operation Manitou is to contribute to the US-led Combined Maritime Forces, a 31-nation partnership focused on defeating terrorism, preventing piracy, encouraging regional cooperation and promoting a safe maritime environment.
Townsville lad, LS Tymrakiewicz operates the ships telecommunications systems, including automated networks, data links and satellite systems, to ensure contact between ships at sea and bases ashore.
LS Tymrakiewicz is a former Ignatius Park student and studied at James Cook University in Townsville.
"Accounting is not for everybody, so I decided to join the military in 2006 and see the world," he said.
"I have always been interested in computers and information technology, which meant I was well suited to my chosen trade."
Navy has conducted maritime security operations in the Middle East region since 1990.
LS Tymrakiewicz said he last deployed to the region in 2010/11 on HMAS Parramatta during Operation Slipper.
"We were conducting counter piracy patrols in the Red Sea with Combined Task Force 151," he said.
"Now the main task for Darwin is to support Combined Task Force 150 (CTF 150) in maritime security and counter terrorism operations.
"Our job will be to intercept and dispose of illegal drugs that provide funding for terrorist organisations.
CTF 150's area of operations spans more than two million square miles, covering the Red Sea, Gulf of Aden, Indian Ocean and Gulf of Oman.
Darwin joined the French Carrier Strike Group Charles de Gaulle from February 23-25 to provide escort, force protection support and combined training operations in the Gulf of Oman.
The Charles de Gaulle battlegroup is deployed to the Gulf to participate in operations against Islamic State militants in Iraq as part of US Naval Forces Central Command's Task Force 50.
LS Tymrakiewicz said Darwin travelled through the South China Sea and South East Asia on the way to the Middle East and visited Thailand, Indonesia and India during the journey.
"We have a fantastic crew on Darwin and we spent many months preparing for this mission since I joined the ship in March last year.
"During our Mission Readiness Exercise we focused on boarding party tactics and force protection procedures to ensure the Ship's Company know how to respond to an incident."
LS Tymrakiewicz said his family still lived in Townsville and he usually made it home at least once a year.
"I have been lucky to spend my time on frigates based in Sydney, which means we spend a lot of time away," he said.
"It can be a challenge to leave the family and friends behind, but I love the travel."
