The Tasmanian Legislative Council is the upper house of the Parliament of Tasmania in Australia. It is one of the two chambers of the Parliament, the other being the House of Assembly. Both houses sit in Parliament House in the state capital, Hobart. Members of the Legislative Council are often referred to as MLCs.
Australia has four chambers in its federal government.
The text refers to the government of Tasmania, but does not mention the structure of the national government of Australia, so we don't know. It's difficult because two chambers are mentioned in the text, so this confused it.
