Does this help, Bob? Copied from an issue of the mag 'Folk Review' in Cecil Sharp House at a time when I was too young to have learned proper documentation of my sources:

[?:] "I watched the parade and all the crap that goes with the so-called glory. I was annoyed by the whole thing. The people on these parades generally never saw action. All the real soldiers were killed. In Australia, ANZAC Day is merely an excuse for a booze-up. When I get annoyed by things I write songs about them." Bogle wrote the song in seven hours. [...] He first sang Matilda in the Kingston Hotel, Canberra. He forgot some of the words, earned a few polite handclaps and then dropped the number from his repertoire. He dug the song out again for a song festival in Brisbane. The judges placed him and Matilda third, but their decision caused a near-riot with the crowd who felt he should have won. The resulting publicity established Matilda. John Curry sent it up the charts. [...] It caught on in the UK and was recorded by June Tabor, Alex Campbell and Iain MacKintosh.
