Frederick,
We'd be glad to help with your wall project.  By the way, I've got some relatives in Australia, but they live near Adelaide!  My wife visited a number of years ago, and my father-in-law usually travels there about every 2 years, and spends a few weeks traveling from Perth to Sydney.
Anyway, back to your wall question ..... Read More ...
