We had to get from Toowoomba in Queensland to Ballina in New South Wales and chose to go the slow way. It would have been quicker to go via the freeways at Brisbane and the Gold Coast, but we went via Warwick, Woodenbong and Kyogle - up and over the mountain range, down the river valleys, on twisting and in places bumpy roads.
It was a very interesting day, and in the process we crossed the border just south of Killarney. It's marked by a sign, a cairn and a little marker put in by the Brisbane and District Trail Horse Riding Club. The border was surveyed by Francis Roberts and Isiah Rowland between 1863 and 1866 and as we travel on the sealed roads in comfort it's amazing to imagine the effort it must have taken to survey the area.
