When I type Verses Popular and Humorous into ye olde searche engine, first thing that comes up is a site at Sydney University library - but, alas, the pdf available there has no page numbers. It's the third poem in, starting on the 4th page of poetry. The second site that comes up is from the Gutenberg project - and that doesn't have any page numbers either. Then the National Library of Australia pretends to have it online, but that's just a link back to Sydney University. Then there's the oldpoetry site - but I can see Charley has been there, and he has probably been to all the other sites, too, and could have saved us some time by telling us so.
It looks like there's hard copy at the National Library, but it's too far to walk.
