Dubbo Grove Licensed Post Office licensee Leanne Fulwood reported of a "huge influx of parcels", which she attributed to the social media movement that started in October.

"People are bringing in, one particular customer, she's brought in between 40, 50, 60, 80 parcels each time she comes in," Ms Fulwood said.

The rise in lodgements had continued this month.

"There has been a change, Christmas parcels coming in, but this online shopping with Buy from the Bush, there hasn't been a rest," Ms Fulwood said.

"Normally you can tell when people are preparing to post their parcels for Christmas, but this year it's been a continuation."

It's a trend seen across the Orana region.

Coonamble, which has a population of about 2750, saw more than 1000 parcels fly out the post office door last month, a 214 per cent increase, thanks to campaigns like Buy from the Bush.

Australia Post data across regional post offices in drought-affected areas with a retail lodgement volume of more than 1000 for November showed that 25 post offices in regional NSW including Coonamble, Molong, Gulgong and Condobolin experienced substantial growth when compared to the same time last year.

Australia Post's NSW/ACT state general manager Christine Walker said the figures helped to demonstrate that these campaigns were really making a difference.

Ms Fulwood, who went into partnership with sister Janelle to take on the post office six years ago, said the movement was helping their bottom line.

"It increases our money side of things, as far as stock, they're buying stock from our shelves," she said.

"I hope it does [continue] for everyone's benefit..."

Buy from the Bush was launched by Grace Brennan of the Warren district to help retailers in drought-hit communities.
