Dubbo Athletics Club has been conducting its weekly club meets at the facility since earlier in the month, however a number of the people responsible for the construction of the multimillion-dollar facility will be on hand today to officially open the centre.

Dubbo mayor Mathew Dickerson said the project was identified as a priority in the Dubbo 2036 Community Strategic Plan and would be a drawcard for major athletics meets.

"Barden Park will benefit all users including athletic clubs and schools in Dubbo and across the region. The facility also significantly enhances the potential for Dubbo to host state and national events and with that comes even greater economic benefits for the City," Dickerson said.

Deputy Prime Minister and Minister for Infrastructure and Regional Development Warren Truss said the Barden Park Regional Centre of Excellence for Athletics is now an international standard athletics track and field venue.

"Barden Park can now cater for up to 1000 competitors, up to 2000 spectators depending on ground configuration, and can be used 365 days a year in all weather conditions," Mr Truss said.

NSW Deputy Premier and Member for Dubbo Troy Grant said the state-of-the-art facility will be a drawcard for sporting events across the state.

"This is a great boost for the region, especially with the 14 full-time jobs created as a result of the economic activity generated by this project," Mr Grant said.

Federal Member for Parkes Mark Coulton said the redevelopment included the construction of a 600-seat grandstand with undercover seating.

"The new-look Barden Park also has the capacity to provide overnight accommodation for 35 children and two adult supervisors, which will be available at low cost so families can afford to send their kids to development camps on site," Mr Coulton said.

The Australian government provided $3,477,223 towards the project, with the NSW government contributing $575,000 and land valued at $681,000, and Dubbo City Council investing $958,130.
