Duckadang is bounded on the eastern side by Avoca Creek and the Brisbane River on the southern side. Avoca Creek only flows after good rains and in dry times the Brisbane River reverts to waterholes with the Duckadang waterhole being one of the deepest due to its rock bottom.
The small township of Linville is located 12 kilometres southeast of the camp. On the 19th August 1841 the Balfour brothers took up the Colinton Run. This covered an area of some 336,000 acres and included the present site of the town of Linville through to Avocavale to the west of Duckadang. The Balfours established cattle yards called the 'Nine Mile Yard' in the area around Greenhide Creek (south of the present town) and by 1886 a small private township had developed.
The 'Nine Mile Receiving Office' opened there in 1898. The town survey of 'Linton' was lodged on the 6th December 1901. This original plan was situated approximately one kilometre south east of the present town and the residents chose the name Linton by dropping the syllable 'Co' from Colinton. The postal authorities did not favour this as there was already a place in Victoria called Linton. A compromise was reached and the name was changed to Linville in 1905. The Receiving Office became a Post Office in 1910 and the Linville State School (situated on the right as you drive in to town) celebrated its centenary in 2001.
The first industries in the district were sheep, beef cattle, dairy cattle and pigs. Beef cattle are the main pastoral industry today.
Red cedar, silky oak and hoop pine were also cut for the timber industry. The Linville Sawmill still operates and is situated on the left as you drive through town towards Duckadang. The area also has deposits of gold and coal but not enough to mine.
