Well I guess everyone has their own idea of what's funny.

I mean here's some https://www.winetraveler.com/australia/funny-town-place-names-in-australia/

we've got silly names like bottle shop for where we buy booze (sells bottles), usually shortened to bottle-o, similarly you have stuff like service station -> serv-o.

Indigenous place names often have "wo" sounds and repetition, you get stuff like wagga wagga etc. Consequently we tend to say "it's in woop woop" if something is the arse end of nowhere.

Plus there's the sheer lack of imagination in the English colonial naming. I mean "new south Wales"? really? Not even like "yeah this is like Wales" someone looked at a fucking dry sandy cliffy bay and said " you know what this fucking reminds me of? Wales. Wait no, the southern part of Wales"
