Orange360 general manager Caddie Marshall said it was hoped the centralised booking scheme, where everyone from motel and hotel owners to people with a spare room have been encouraged to join, would be successful.

"This project represents a huge opportunity for the accommodation sector to reap the obvious economic benefits of expansion this will bring to the region," she said.

"It should also be seen as a unique chance for the local tourism industry to reinvest in itself to standardise and raise the level of hospitality service being delivered across the region.

"Our ultimate aim for the industry accommodation booking program is to enhance the Orange region's reputation as a destination of choice by encouraging visiting workforces to consider making a permanent move to the region or to continue returning to the region in the future as leisure visitors bringing their friends and families."

Orange360 will host several Industry Accommodation Forums in early December in the Orange, Blayney and Cabonne council areas.

Up to 400 workers are expected in the region to work on a $685 million expansion program for the Cadia mine.

Ms Marshall said Orange360 would assist Newcrest Cadia Valley Operations in finding accommodation for temporary and residential workers over the next two-five years.

She said the trial centralised accommodation plan was looking for the "hidden additional beds" in the region outside of hotels, motels and caravan parks.
