Walkers Limited was an Australian engineering and shipbuilding company based in Maryborough, Queensland.

[5] In 1884, the firm began work on five hopper barges for the Queensland Department of Harbours & Rivers.

During construction the decision was taken to convert them to also serve as auxiliary gunboats, which made them the largest warships built in Australia before federation.

Post war naval contracts included seven Attack-class patrol boats in the late 1960s and eight Balikpapan-class landing craft heavy in the early 1970s.

Walkers Limited is regarded as being one of Queensland's greatest companies spanning 150 years in the engineering manufacturing sector.
