When I search in Google Books for certain distinctive phrases from the poem, for example "And the other - only a Q" it turns up a book called "Australian Folksong, Volume 8" by Ron Edwards (Kuranda: Rams Skull Press, 1994).

This book is not viewable online, but WorldCat.org shows me that copies are held by the National Library of Australia, the State Library of Queensland, and Curtin University. (There may be others near you, but those are the libraries in Australia whose catalogs are accessible through WorldCat.org.)

I assume you are in Australia.

WorldCat.org also tells me that "Australian Folklore Society Journal" is held by the National Library of Australia, Monash University Library, the State Library of Victoria and Curtin University Library.

If you can't conveniently visit any of these libraries, I recommend you print out this information and take it to your local public library, or any library where you have borrowing privileges, and ask a librarian whether they can help you get a book.

Sometimes libraries will photocopy selected pages for you and mail them to you, for a fee.
