Combining hauntingly beautiful photographs with classic Australian bush poetry, Last Train to Brisbane takes a nostalgic romp through Brisbane's scenic rim in search of what remains from our railway past. From Gympie through the Mary and Brisbane Valleys, and onto the Southern Downs city of Warwick, poet and Award-Nominated author Phillip Overton takes his lifelong love of the rails on the road. The result is this tribute to the small country towns where it was once possible to catch a train to Brisbane.
