Its not a case of there "may have been some fine colonial joinery", the fact is that there is a significant body of superb Australian made colonial furniture. I know for I have seen countless examples of it down here in Tasmania, in National Trust properties, at the Museum in Hobart, let alone at major antique auctions and specialist antique dealers around the State etc.
We down here in Tassie have had some of the very best of colonial furniture, let alone domestic architectural features, given that Tasmania was the second colony in the country, with a significant colonial landed gentry. They wanted the very best and usually could afford it.
I have to agree with the comments that rustynail makes. It simply makes sense.
