The RAAF Darwin River Quarry was established to supply blue metal for the construction of 11/29 the then new airstrip at RAAF Darwin. Located near Darwin River Dam the quarry closed in the early sixties. Commonwealth Railways train being loaded at the Darwin River Quarry chinaman for transport to RAAF Darwin. The blue metal quarried by 5ACS at Darwin River after rough crushing was sent to Darwin for fine crushing and use in the construction of the main runway.
A twenty minute DVD of 5ACS taken by the RAAF film team showing most facets of the Darwin airstrip construction including a short piece on Darwin River Quarry is now available from the NAA [National Archives of Australia] for about $25. If you would like to try before you buy I think you can arrange a viewing at any of the NAA buildings around Australia.
