IT HOUSED thousands of soldiers as the state's first purpose-built military camp in World War II, now the Ingleburn Military Heritage Precinct, together with Mont St Quentin Oval, has been recognised for its historical importance.
Both sites have been listed on the State Heritage Register, which features more than 1600 sites that are culturally or historically significant to NSW.
NSW National Servicemen's Association president Ron Brown welcomed the announcement.
"The camp itself was built in five weeks in 1939 for the troops who went over to World War II and it was used in the Korean and Vietnam wars," Mr Brown said.
"It is a very significant site and we're hopeful it will be utilised in time to come."
Mr Brown said the Mont St Quentin Oval could be used as a sporting field and the military precinct could host open days and tours.
Campbelltown state MP Bryan Doyle said many generations of ex-servicemen and their families had passed through the important local site before active service or national service training.
"I know my father was one of the many who proudly undertook National Service at the Ingleburn military camp," he said.
"It is important that we preserve our history for future generations to appreciate and honour."
The listing means the site is now legally protected as a heritage item under the NSW Heritage Act.
Any major changes to the site would have to be approved by the NSW Heritage Council.
