The South West Development Commission office was relocated back to the old post office building on Friday, March 8.
Regional Development minister Alannah MacTiernan officially opened the new office by cutting the ribbon, alongside Collie-Preston MLA Mick Murray, South West Development Commission acting chief executive officer Rebecca Ball and Collie River Valley Marketing Group chair Julie Hillier.
The state government agency was moved due to its more prominent and accessible location.
An on-site, hot-desking area acts as a central hub for other agencies working in the town on initiatives, including those requiring a multi-agency approach to stimulating economic diversification and job creation.
Regional Development minister Alannah MacTiernan said it was great to be able to open the new office.
"This used to be the office. It's a beautiful building and it really represents the heritage of Collie," she said.
