They include Queensland, New South Wales, Tasmania, Victoria, Australian Capital Territory, Northern Territory, South Australia, and Western Australia.
The Clarence River flows through the Northern part of New South Wales. Wales is also a state, not a territory.
Sydney is in the state (not territory) of New South Wales.

The country between Scotland and Wales is... England.
Strictly speaking, Canberra is neither in New South Wales nor Victoria. It lies within the Australian Capital Territory, a quite separate territory from any of the states. However, the ACT is a territory completely encompassed by NSW, utilising territory ceded by NSW for the purpose of a federal capital in 1911.
New South Wales is not a country. New South Wales is a state in the country of Australia.
