The Association was formed on Wednesday 13th March 1946 at a meeting held at the Deaf and Dumb Society Rooms in Sydney. The minutes note a proposal from Mrs L. O'Malley Wood (President of the 2/1-2/2 Comfort Fund) that the "two units be amalgamated" and known as "2/1-2/2 Pioneer Battalions Association". It was also proposed and accepted by the 118 members present, that the annual subscription be 10/- per member and the Association march together on ANZAC Day as one body.

The history of the 2/1st and 2/2nd Pioneer Battalion’s - as written by the Australian War Memorial - are covered as separate stories under this heading. There are also links to these sites under the “Links” heading.

The Pioneer News has several articles covering the formation and history of the battalions and some of these stories have been extracted under the “Extracts” heading.

In particular a short history of both the 2/1st and 2/2nd Battalions is covered in Extracted Story #19.

A book with reference to the 2nd/2nd Pioneer Battalion was published in 2018: “The Lost Battalions” by Tom Gilling, Published Allen & Unwin $32.99 (reviewed in the Sydney Morning Herald (Spectrum) 29-30 September 2018).
