Forster (/ˈfɒstəɹ/ FOST-ər)[3][4] is a coastal town in the Mid North Coast region of New South Wales, on country of the Worimi People, Australia, in the Mid-Coast Council LGA, about 308 km north-north-east of Sydney.

[6] The first post office in Forster opened on 1 October 1872, with John Wyllie Breckenridge as postmaster at a salary of £10 a year.

A bridge over the Coolongolook River that marks the entrance to Wallis Lake was built in 1959 linking Forster and Tuncurry and replacing the punt service that had operated since 1890.

Because of its close proximity to Sydney, just under 4 hours drive, Forster–Tuncurry has established itself as a popular summer holiday destination; in the hotter months the population increases considerably.

Forster experiences a humid subtropical climate (Köppen: Cfa); with warm summers and mild winters; and with a moderately high precipitation amount of 1,176.4 millimetres (47.99 in).
