Allawah is a quiet, residential neighbourhood straddling the main southern rail line heading into the Sydney CBD. Its access to the train station, schools, and shopping has made it popular with professionals and families. It's also a quick ride to the calm beaches abutting Botany Bay.

Allawah is bordered on the north by Hurstville and Bexley, on the east by Carlton, on the south by Carlton and Blakehurst, and the west by South Hurstville and Hurstville.
