It depends entirely on the value of the stamps. In 2010, a standard letter currently requires a stamp or stamps to the value of 60c within Australia.
The cost would be different from each town to it's destination.
The rate is $2.10 ( Australian) from up to 50 grams via air mail from Australia to the US.
