A ceremonial parade marked the establishment and first birthday of 13th Brigade's 13th Engineer Regiment, the first of its kind in Defence.
July 1 is celebrated as the Royal Australian Engineer Corps' - and now the unit's - birthday.
The regiment's roots go back to 13 Field Squadron, which traces its origins to the 7th Field Company, formed in 1907.
In 1909 it was renamed the 4th Field Company, and changed to the 6th Field Company in 1910; the 13th Field Company was formed on July 1, 1912.
Commanding Officer 13th Engineer Regiment Lieutenant Colonel Lachlan Robertson said the 13th Engineer Regiment structure had two squadrons - the existing 13 Field Squadron and a new specialist 22 Engineer Squadron - which added science, technology, engineering and maths [STEM] capabilities such as innovation, experimentation, project management, and technical reconnaissance.
"These will be applied through an integrated approach with academia, industry and government partners in support of national defence," Lieutenant Colonel Robertson said.
"Along with the specialist STEM capability, 13 Engineer Regiment will continue to provide combat and force support engineering capabilities to enable integrated manoeuvre.
"The establishment of 22 Engineer Squadron has seen a number of specialist service officers recruited from industry and the recruitment of 'any corps' personnel. Combining these specialists, with a focus on new ideas and concepts, will strengthen Army's innovation and experimentation capability.
"13th Brigade is continuing to be a test bed for military innovation and transformation for greater Army."
