Well ... at least most of us can spell Paterson as 'Banjo' did!
Incidentally, you don't need to go too far into the works of Paterson's contemporary, Henry Lawson, to notice that Henry was either aware of ... or inspired ... the verses you quote.
It's also worth noting that these did not appear, in print, until after 'Banjo' Paterson's poem - attached to Christina McPherson's recollection/arrangement/quotation from the Craigielea tune had popularised the local (south-east Queensland) expression "walting Matilda" for carrying a swag.
