In 1795, George Bass, Matthew Flinders and the boy servant William Martin began an expedition to explore parts of the colony on a small boat called the Tom Thumb.

They sailed into Botany Bay and explored the Georges River, twenty miles (32 km) beyond previous expeditions to the area that is now Garrison Point.

His older brother, George Jr. had held this position until his death in 1820 following a riding accident on the Macarthur property at Camden Park.

Garrison Point and Lake Gillawarna form the southern part of a larger reserve called Mirambeena Regional Park that extends into the adjacent suburb of Lansvale.

A short distance south from Garrison Point is Kentucky Reserve, another recreational park area overlooking the Georges River, adjacent to Henry Lawson Drive.

After WW2 Georges Hall expanded significantly with a large number of Eastern European refugees building homes in the area after migrating to Australia in the late 1940s and 1950s.
