Tax Avoidance 101: Establish business in tax haven (Isle of Man, Cayman Islands etc). Have that business provide a service to your Australian based businesses. Charge exorbitant fees for this service making your Australian business barely, if at all, profitable. Pay no tax in Australia and pay no tax on huge off shore profits.
P.s. This is the actual reason plain packaging was enforced on cigarettes. The cigarette brand names were based offshore and charged huge fees for the use of the logo/brand in Oz. Move the profit offshore, pay little to no tax. Clever move by the fed government to restrict the use of the brands to stop this behaviour and keep the profits in Oz.
