As the name suggests, Mount Lofty Group are located in the Adelaide hills just south and east of Mount Lofty.

It consists of eight operational Brigades and an Operational Support Unit (OSU).

The Operational Brigades have been established for many years.

The OSU is currently considering its status and has recently submitted a request to be upgraded to a Support Brigade.

The role of the OSU is to carry out behind the scenes support for larger incidents, they will not take a front line role.
