Today, the 7th Brigade is part of 1st (Australian) Division and is based in Brisbane, Queensland and is composed mainly of units of the Regular Army.

[3] The 7th Brigade was re-formed in early 1915 as part of the First Australian Imperial Force, which was raised for overseas service during World War I.

Under the command of Colonel James Burston, it consisted of four infantry battalions raised in Queensland, South Australia and Western Australia—the 25th, 26th, 27th and 28th Battalions—the brigade was assigned to the 2nd Division in July 1915.

[4] After being deployed to Egypt, the brigade was sent to the Gallipoli peninsula in September 1915 as reinforcements[5] for the Allied force that had landed there on 25 April, and were attached to the New Zealand and Australian Division, occupying positions north-east of Anzac Cove.

In 1921, the decision was made to reorganise the part-time Citizens Military Force to perpetuate the numerical designations and battle honours of the AIF, as well as its divisional structure.

[22][23] At the beginning of the war the brigade was primarily responsible for the defence of South East Queensland, with battalions located at Chermside, Cabarlah and Maryborough.

[26][27] In August, the brigade took part in the Battle of Milne Bay along with elements of the 7th Division, during which the Australians struck a considerable blow to Japanese intentions in the Pacific, inflicting upon them their first major defeat on land of the war, turning back an attempted landing to secure the strategically important airfields that the Allies had built in the region.

[28] Following the battle, the brigade maintained a garrison around Milne Bay until March 1943 when they were moved back to Port Moresby.

In April, the brigade moved to Donadabu, occupying a position around Sogeri Plateau,[29] where they undertook further training and remained poised to reinforce troops around Wau of Lae, if necessary.

[31] In mid-1944, the brigade was deployed overseas again, firstly to Madang where it undertook garrison duty and patrolling operations to locate Japanese stragglers, before moving to Hansa Bay in August.

[34] In 1948, the Citizens Military Force was re-formed on a voluntary basis,[35] and 7th Brigade was subsequently re-raised at Kelvin Grove in Brisbane, Queensland on 7 May 1948 under the command of Brigadier William Steele.

[38] In late 1964, conscription was reintroduced, albeit in a different form which focused mainly on bolstering the Regular Army to meet commitments in Southeast Asia.

During the Pentropic years, brigade formations had been discontinued, although their headquarters units had remained in many cases, to improve the flow of information.

[47] In April 2015, around 100 personnel from the 7th Brigade deployed to Iraq as part of Task Group Taji, to provide training for Iraqi forces fighting against ISIL, alongside troops from various other nations including New Zealand.
