The facility, which belongs to the NSW State Emergency Service, was officially opened at the weekend.

Whether it's a building collapse or a car crash - volunteers from the SES and NSW Rural Fire Service as well as police officers and Fire and Rescue NSW firefighters will be able to maintain their skills.

The purpose-built facility is equipped for night training as well being able to simulate rescues from heights and depths.

Having the facility in Griffith means less time travelling to Sydney or elsewhere for emergency services personnel.

While it's equipped for big jobs, Griffith SES unit's Local Commander Steve Mortlock said rescues from sinks and bathtubs could also be simulated.

"The only time that I've seen anything like this has been in Sydney," he said.

"It's good to have a facility that can offer the challenge, without the risks."

Griffith SES volunteers hosted Fire and Rescue NSW over the weekend as they gave the facility its first run with multi-agency training.

Mr Mortlock said he believed it was the first time that Fire and Rescue NSW and the SES held joint road crash rescue training.

It's expected other SES branches and firefighting brigades will be training at the facility in future.

"NSW SES volunteers and members from other emergency services will be able to maintain their rescue skills in this new purpose-built training facility," SES Commissioner Kyle Stewart said.

New training equipment at the facility was paid for with ministerial grants, with Griffith City Council and local businesses helping with the surrounding infrastructure and new signage.

Mr Mortlock said the efforts of the Griffith SES volunteers and locals were instrumental in helping to deliver the training facility, and without them it would be been impossible for the project to be completed.
