As a bit of trivia about old sawmills. The town near me, Wauchope, NSW (now called Wauchope, the Timber Town by the tourist people) used to support well over 20 sawmills within the town itself and another 20 odd mills out in the bush. Some of these mills only employed 2 men and processed waste from the larger mills. They cut fence pailings, garden stakes, oyster sticks and more. Some cut weather boards, flooring, cladding and lining boards, other mills cut big timbers and there was also a NSW Government Railway Mill that just cut timber for the railways dpt.
Those times are long gone now. There are only a couple of mills working in the area today, one being run by the Daughter of the man who built it way back in the mid 1940's. This lady is now in her 60's so how long that mill will keep going, who knows.
