The Australian Department of Defence (ADF) commenced a project in East Timor (also known as Timor-Leste) in 2013 called Exercise Hari’i Hamutuk which was designed to increase the engineering capabilities and interoperability between the ADF and F-FDTL and other supporting nations, allowing techniques and procedures to be shared and refined by subject matter experts between militaries. Twenty-five ADF members, predominately from the Australian Army’s 1st Combat Engineer Regiment, worked with the F-FDTL to carry-out construction and maintenance tasks at Baucau Military Base and Military Police Base Baucau, as well as a solar panel installation at a military outpost near Cova, west of Dili.

The exercise first occurred in 2013 with the aim of enhancing the skills of the F-FDTL while continuing to build on the strong relationship forged in the 10 years of Australian deployments to Timor-Leste in support of peacekeeping operations.

A tank was needed for this project and CPL Tim based in Australia’s Capital Territory reached out to us to commence this custom project.

As Timor-Leste is a young, developing country with ongoing infrastructure works, the key drivers for the fuel facility were:

  • Ease of use
  • Reliability
  • Ease of service & maintenance

Further to this, power was not available at the fuel site. Through discussions with CPL Tim Birrer, Fuelchief representative Denis Dardengo, offered the Fuelchief Praxis PX1-5000L overhead diesel tank. This allowed operators to easily dispense fuel without the requirement for power or an electric pump. The Praxis tank was fitted with an isolation valve, strainer, hose and manual nozzle which met the brief; simple to use, reliable & simple to maintain.

The outcome was rather different to what most of our tanks look like! however, successfully met the needs of the project to provide fuel for the military site. The custom made Praxis is was commissioned in September 2020 and remains a vital addition to The Australian Defence Force’s Exercise Hari’i Hamutuk.
