Australia Post said that its monopoly letter service (stamped and bulk business mail) made a $269 million loss last financial year but claims that if the price of stamps was increased to $1 from next year, that loss would reduce to $70 million this financial year and turnaround to a forecast $84 million profit in 2016-17 – based on its target that 80 per cent of users take-up the slower mail service.
