Decmil has been leading the way in large scale, complex project delivery for over 35 years thanks to our depth of experience and our committed ‘make it’ attitude.

Blue chip clients in the infrastructure, mining, oil & gas, commercial and industrial sectors rely on us to provide specialist teams to meet their needs for a range of services including design, engineering, construction, fabrication, maintenance and telecommunication projects across Australia and internationally.

We deliver these services largely in regional and remote locations, often with challenging logistics.  Decmil’s three business units, Construction & Engineering, Accommodation Services and Technology, assemble the right teams and develop collaborative relationships to ensure that every project we participate in is delivered safely, on time, on budget and to the very highest standards.

Our reputation is built on our ability to ‘Make it’, and our record of success attests to our commitment to exceeding our clients’ expectations and the repeat work that results from this.
