G'day again Q,

This one doesn't have any real 'connection ... descent' relationship to the original subject song ...

Given the pioneering conditions / early gold rush activities, &c, of the mid 1800s, in eastern areas (... to-be-states ...) of the fairly newly 'European-invaded' Australia, we have to regard a location such as '... in an old bark hut' as meaning:

"reasonably well settled ... at least for the current 'gold rush' / land 'selection' / property sales / ... any other chance of settling down in this area ... hanging onto this spot ... for now!

Organised / officially-sanctioned / land settlement schemes were only just getting going from the 1860s ... and an easy way to pass on the news was in song!

Regards,

BobB
