Queensland’s gunboats were fitted with a range of armament during various periods in their service lives.
Gayundah was originally fitted with an 8-inch breech loading gun (for’d), a 6-inch breech loading gun (aft), two 1.5-inch quick-firing guns, and two machine guns.
Paluma, primarily used as a survey vessel for the first ten years of her service was disarmed for that period. Her main 8-inch gun was never fitted in the first instance, being shipped separately aboard a commercial vessel rather than fitted for her delivery journey.
The guns fitted were of the following types:Details of the various guns fitted to Queensland's gunboats during their service lives.
