Narrow-gauge railways in Oceania

Following the success of the narrow gauge in Queensland, several narrow-gauge lines were built in South East Australia.

Until closure in 1958 Perth had the only narrow-gauge tramway network of any considerable extent in mainland Australia.

The Northern Territory adopted narrow gauge when it was still part of South Australia, and a North–South transcontinental line was planned from Adelaide to Darwin in the 1870s.

Four common-carrier lines in Victoria were built to the 2 ft 6 in (762 mm) narrow-gauge standard, to serve local farming and forestry communities.

Sections of two lines (Belgrave to Gembrook and Thomson to Walhalla) have been restored as tourist railways.

Fiji used to have narrow gauge railways for harvesting sugar cane, and several horse-drawn street tramway systems.

This terrain has necessitated a number of complicated engineering feats, notably the Raurimu Spiral.
