The clubs first premiership in 1897 was won with Port Adelaide full forward Alex McKenzie.
Railways FC is the club's main rival, this is due to the fact both are based in Kalgoorlie and share the same home ground.
The other major rivalry is shared with Boulder FC, and this is somewhat of a microcosm of the (antiquated) rivalry between the towns of Kalgoorlie and Boulder before they fused to form the city of Kalgoorlie-Boulder.
The club finished as runners up in 2012 after losing to Railways in the Grand Final (7.8-50 to 14.11-95).
The Kalgoorlie Colts side also experienced success capping off an undefeated season defeating Boulder Tigers in the Grand Final (14.12-96 to 9.10-64)
