The major production area in NSW stretches south from the Macintyre River on the Queensland border and covers the Gwydir, Namoi and Macquarie valleys.
With changing weather patterns and essential irrigation changes in the national scheme cotton growing is moving south each year.
Extensive areas of new cotton are now grown along the Barwon and Darling rivers in the west and the Lachlan River areas as well, as the Riverina along the Murrumbidgee River in the south. In Queensland, cotton is grown mostly in the south in the Darling Downs, St George, Dirranbandi and Macintyre Valley regions. The remainder is grown near Emerald, Theodore and Biloela in Central Queensland.
