About Us

History

Heli-Muster was started back in 1976 by John Weymouth as a two-helicopter aerial cattle mustering operation. The company flourished in subsequent years to become the major player of the Australian mustering industry.


At its peak in the mid 1980's the company had over 26 mustering helicopters across the Top End, which consisted of Bell 47’s and Kawasaki KH4’s until the advent of the more modern Robinson R22, which was introduced in the late 1980’s.


Heli-Muster NT now offers an expanded charter, fixed wing and turbine division, run under subsidiary HM Air and offering a variety of specialised aviation services across the NT and beyond.
