Mustering is done with horses or vehicles including all-terrain vehicles (ATV), and some of the large cattle stations use helicopters or light aircraft to assist in the mustering and surveillance of livestock and their watering points. Cattle mustering in the Outback and the eastern ‘Falls' country of the Great Dividing Range often necessitates days camping out in isolated areas and sleeping in a swag (bedroll) on the ground with limited food choices. Damper is a traditional type of bread that was baked by stockmen during colonial times, or nowadays when the bread supply has been exhausted. It is made with self-raising flour, salt and water and is usually cooked in a camp oven over the embers of a fire. In these areas the days in the saddle are often very long as the cattle have to be mustered and then driven to yards or a paddock where they can be held. After the stock have been yarded they may then require drafting prior to branding, shearing or whatever procedures are required or have been planned.
