The cost of sending a letter with Australia Post will soon cost more after the Australian Competition and Consumer Commission (ACCC) decided not to step in. “Our findings suggest Australia Post will still fall slightly short of recovering the efficient costs of providing these services, even with the proposed price increase.” “The ongoing decline in letter volumes has now reached levels not seen in Australia since the late 1930s,” Australia Post said. The ACCC decided not to refuse the proposed price increase as Australia Post tries to recoup annual losses due to a declining customer base. “Australia Post is not alone in facing this challenge, with this letter decline being experienced by international postal operators worldwide.”
