Australia Post says it has no plans to replace some door-to-door delivery services with regional mail hubs, but admits it did discuss the possibility.
Liberal Senator Ian McDonald has used a Senate estimates hearing to question Australia Post officials about the potential use of mail hubs.
Australia Post official Don Newman says the organisation considered a system in which people travelled to a community mailbox to receive their letters.
But he says the feedback from the public was not good.
"They're used around the world. There was no doubt there was a discussion in Queensland with a local group of people last year just to sound out what people felt about it," he said.
"I think the reaction from our customers and the press have been fairly strong."
