G'day GUEST of 17 Apr 13 - 05:58 AM,

You interpretation of "~ Mudgee Mailbags" sounds reasonable ... but it must have a good bit of age about, for Australian vernacular.

I can remember that the train caught, from Sydney, to head off west of the Great Dividing range, was always "The Mudgee Mail" ... and I certain that my Dad's pre- and post- WW2 bushwalking was a heavy user of the same ""Mudgee Mail" service ... as well as the early morning "Mountains to Sydney" Monday, first light commuter service!

Of course, it may be the expression reflects reaction to the heavy load of Sydney ... to the Bush ... mail that steamed out of Sydney every evening!

Regard(les)s,

Bob
