G. Austin was one of the MACOs assigned to Enterprise for its Delphic Expanse mission in 2153.
He was part of Malcolm Reed's team sent to repel a Xindi-Reptilian boarding party who was attempting to secure the capture of Rajiin. Austin was hit by a "glob" fired from a Xindi-Insectoid soldier's weapon, which resulted in Austin's death. (ENT: "Rajiin")
- Austin was played by uncredited stunt actor Kevin Derr, who would go on to play Corporal Kelly.
