Why Telecom Services, Goods, Cost of Living is Expensive in Australia

In a country like Australia, most industry verticals follow 3 or 4 pillar models like Banking (CBA, NAB, ANZ, Westpac), Retail (Coles, Woolies, Aldi), or Mining (BHP, RioTinto, Fortescue) Telecom Industry is heading towards a 4 pillar model. Since most industry verticals are in oligopoly, products & services are priced as status quo or skimmed, and economical pricing is missing in most cases, resulting in higher prices for consumers & higher cost of living. Besides, key players are opting for decentralization to grow and find new revenue streams.
