sentences:  It is the start of the Christmas holidays, and John plans on going to Sydney to be reunited with his girlfriend Robyn, but first he must travel by train to the nearby mining town of Bundanyabba – known by the locals as "The Yabba" – in order to catch a Sydney-bound flight.Upon arriving at The Yabba, John goes to a pub, where he meets the local policeman, Jock Crawford, who befriends him after both drink repeated glasses of beer at the pub and an RSL club, where they witness an unnerving ANZAC memorial service.Crawford then introduces him to the illegal game of two-up, and to Clarence "Doc" Tydon, a vagrant, alcoholic medical practitioner who questions John's contemptuous view of The Yabba and its populace.
