[1] It is a settlement on the Tyenna River in Tasmania, located 81 kilometres (50 mi) west of the state capital, Hobart and is currently but a remnant of a once thriving rural community.

[2] Tyenna was mentioned as early as 1896, when Mr. T. Stephens presented a paper to the Royal Society of Tasmania on possible land routes to the west coast of the island.

[3] Many settlers had already settled and started to clear the heavy forest[4] in the area when it was officially gazetted as a town in 1918.

The mills were reliant on the Tyenna River and Marriots Falls Creek for steam power.

Before the establishment of the towns of Fitzgerald and Maydena it was the resupply base for Adamsfield for osmiridium miners travelling McCullum's Track.
