It is a village east of the Great Dividing Range and is located in the Southern Highlands region of New South Wales, Australia, in Goulburn-Mulwaree Council.

In the early twentieth century the town was renamed "Tallong" after an Aboriginal word meaning either "tongue" or "spring of water".

In the late 1820s, that portion of Barber's land that would eventually become the township was sold or reallocated to Sydney entrepreneur and mariner Billy Blue.

[5] The village sent an annual exhibit of a tall pyramid of fruit to the Sydney Royal Easter Show; Tallong's apples and pears took top honours several times throughout the early part of the twentieth century.

[6] The population reached 200 in 1920, and a Memorial Hall was constructed to mark the town's growth and record the service of local residents in World War I.

In 1955 the Australian poet and novelist Seaforth Mackenzie drowned while attempting to swim across Tallong (formerly Barber's) Creek near the town.
