Words look great - I'll look forward to hearing it with its tune attached!
Rather interestingly, "cop some stick" doesn't seem to get much mention in the standard works on Australian slang ... but I certainly grew up with the expression!
I've been interested to see that liguistic research, starting around Australia's Bicentenary (1988) and using paper-based questionnaires to define regional word-sets ... all taken on "neutral Territory" - Canberra, in the Australian Capital Territory, during Bicentenary exhibitions ... have shown that Sydney (plus a triangle bounded by Newcastle to the north, Wollongong to the south and Bathurst to the west) has its own distinctive word set ... while all other regions have a great amount in common.
I think we might claim this as a "Sydney Triangle" expression (which is why John from Brisbane didn't have it in his Aussie Glossary (to which I added some extra comments).
I think the expression suffers fron two distinct levels of understanding: 1 - the simple image of being beaten about with a stick ... fair enough and perfectly useful for the song ... and
2 - the totally different set of images that come up when you treat "stick" as 'rhyming slang' (briefly alluded to in my copy of The Australian National Dictionary ... Oxford University Press ... and 1988 ... thus compiled before the research I mention above) where the word "stick" can stand for "dick" - in its phallic sense ... and a whole new, different, set of images are evoked!
Anyway, I'll leave it for the moment ... and keep a close check on the progress of our northern end of your "Tasman Buster" ... our "Southerly Buster" ... the cool, blustery, southerly change that often sweeps away the 38ºC (100º F) heat of a high summer afternoon!
We didn't quite approach 38ºC today ... and the "Southerly Buster" has atarted to cool us down ... so I'll be off to my Monday Night Music Session fairly soon. I'll hope to hear all the song soon.
