Stamps could cost an extra 10¢ from next year, under an Australia Post push as fewer letters are sent around the country.

From January, posting a letter within Australia will cost $1.10 instead of $1 if the Australian Competition and Consumer Commission (ACCC) accepts the Australia Post proposal.

It would be the first rise in stamp prices in four years, when they went up from 70¢ to $1.

"The first thing is, it's really just a bit of a catch-up. We're not really addressing the totality of the losses we have in lettering with this price increase," Australia Post managing director and chief executive Christine Holgate said.
