The Billabong. Taken on a rural property near Tamworth, New South Wales. Billabong is an Australian word used to refer to an oxbow lake, a stagnant pool of water attached to a waterway. Billabongs are usually formed when the path of a creek or river changes, leaving the former branch with a dead end. Tamworth is the Country Music Capital of Australasia, the largest and most fascinating tourist region in NSW; one of the biggest gemstone fossiking regions in the State.
