Every Australian River builder discussed had experience with Bathurst-class corvettes, but not every corvette yard moved up to frigate construction. The distinction shows which firms had demonstrated the capacity to tackle a larger and more demanding escort. Diamantina's builder, Walkers Limited at Maryborough, combined railway work with a shipbuilding history extending back to 1884. Its output included corvettes, two River-class frigates, a Bay-class frigate, patrol boats, landing craft, boom-defence vessels, and auxiliaries. Even its first hopper barges were converted for auxiliary-gunboat service and counted among the largest Australian-built warships before Federation. Repeatedly varied contracts demonstrate a durable ability to answer changing naval needs rather than dependence on one wartime design.
