The crash occurred approximately 3km north of Wollogorang Road.
Two ambulance crews and police are on the scene.
A NSW Ambulance spokesperson said the older male was in a serious condition with abdominal pain and head injuries while the other had chest pain.
The occupants of the vehicle were taken to Canberra Hospital by ambulance.
A helicopter flew in as a precaution, causing traffic on all lanes of the Federal Highway to stop briefly, but was unused.
One northbound lane is closed to allow for the vehicle to be towed.
