Everything about Tharwa Australian Capital Territory totally explained
Tharwa (postcode 2620) is a small
village within the
Australian Capital Territory, 35 kilometres south of
Canberra, the capital city of
Australia.
The village is located on the banks of the
Murrumbidgee River and at the junction of Tidbinbilla and Naas Roads, and Tharwa Drive. The main public buildings are a general store, a preschool and
primary school (now closed), Saint Edmund's Church, a cemetery, a community hall and tennis courts. The annual Tharwa Fair was hosted by the school, and was held in May until 2006.
History
Tharwa is the oldest official settlement in the
Australian Capital Territory, proclaimed a settlement in
1862. Tharwa was named after the
Aboriginal word for
Mount Tennent, the overlooking mountain which is part of
Namadgi National Park. Mount Tennent was named after
John Tennant, who was one the earliest and best-known
bushrangers in the region. John Tennant lived in a hideout on the mountain behind Tharwa from which he raided local homesteads 1827-1828, before being arrested and transported to
Norfolk Island.
Tharwa Bridge, opened on 27 March
1895, crosses the
Murrumbidgee River.
Tharwa Primary School was opened soon after, in
1899. The Tharwa township narrowly avoided being burnt in the
2003 Canberra bushfires. The Tharwa community is currently facing two further challenges: closures and repairs to Tharwa Bridge due to extensive rot in its supporting timbers discovered in 2005 and the
2006-07 Australian Capital Territory budget announcement of its plans to close the Tharwa preschool and primary school at the end of
2006.
Geology
Tharwa is in a different geological structural unit than the rest of Canberra, being on the Cotter Horst. The village itself is built on Tharwa
Adamellite. This adamellite is coarsely foliated and contains
biotite mica. It has been dated at 423 ±6 million years old. This places it in the upper Silurian age.
The outcrop area is extended to the north north west to Freshford, and includes Castle Hill. It goes as far to the west as Sawyer's Gully. To the south it goes close to Angle Crossing, and on the east side is bounded by the Murrumbidgee Fault. The Tharwa Adamellite is part of the Murrumbidgee Batholith.
The latitude and longitude of Tharwa is 35°31'00S 149°04'00E. The
geoid is 19.356 meters above the theoretical ellipsoid shape of the earth at Tharwa. The astronomical measurement of the position on the earth's surface is only very slightly distorted by a non vertical gravitational field 0.3" to north and 0.6" to the west.
Magnetic declination at Tharwa is 11.817 deg east, total field strength is 43108 nT
and magnetic inclination is -66.031 degrees; as at 1 March 2006.
Declination is increasing by 0.004 degrees per year. Inclination is increasing by 0.016 degrees per year (as in the rest of Canberra).
