The 6th Battalion (Royal Melbourne Regiment)
The button displayed on page 42 of Cossum shows the head and front legs of a kangaroo on a torque, surmounting the numeral 6, as within the badge above.
Along with the 5th Infantry Battalion, discussed yesterday, this unit is remembered as part of the 5/6th Infantry Battalion, the cap badge which is below. I don’t believe they have an unique button design.
