This relationship between the few sellers is what differentiates oligopolies from perfect competition and monopolies.

Hence, they retain substantial control over the price they charge for their goods (characteristic of monopolies). In my discussion I will use the Australian airline industry to present how oligopolies operate, and to show the different behaviours and strategies that arise from the interdependence of firms. I will mainly concentrate on the domestic airline market in Australia. The domestic airline market consists of a duopoly of two firms, Qantas and Virgin Blue.
