Truganina is a rapidly growing suburban area with Truganina recording a population of 20,687 at the 2016 census. It is bordered roughly by the Skeleton-Waterholes Creek to the west; Boundary Road to the north; Foundation to the east and the Federation Trail to the south.
The nearest railway stations are Williams Landing which is 3.5 kilometres from the centre of Truganina. Laverton and Hoppers Crossing, both on the Werribee railway line are 5 kilometres from the centre of Truganina. Another similarly distant railway station, Tarneit, at the corner of Derrimut Road and Leakes Road in nearby Tarneit, opened recently as part of the Regional Rail Link project. This would provide V/Line diesel services on the route between Geelong and Melbourne. There are plans for an additional station to eventually be added to the line to service Truganina.
- Truganina was named after Truganini, a famous Tasmanian aboriginal woman.
