Australia Post is increasing the price to send a letter by 43%. Letters will now cost $1 and take substantially longer. More money for worse service! And I do believe that increase is well above inflation. Discuss.

20 gram letter, New York to Los Angeles USPS is 49c. I have no idea where you're getting $1.50 from, even with our terrible exchange rate.
