The New South Wales Legislative Council, often referred to as the upper house, is one of the two chambers of the parliament of the Australian state of New South Wales. The other is the Legislative Assembly. Both sit at Parliament House in the state capital, Sydney. It is normal for legislation to be first deliberated on and passed by the Legislative Assembly before being considered by the Legislative Council, which acts in the main as a house of review.

The Parliament of New South Wales, formally the Legislature of New South Wales, is the bicameral legislative body of the Australian state of New South Wales (NSW). It consists of the monarch, the New South Wales Legislative Assembly and the New South Wales Legislative Council. Each house is directly elected by the people of New South Wales at elections held approximately every four years. The legislative authority of the parliament derives from section 5 of the Constitution Act 1902 (NSW). The power to make laws that apply to New South Wales is shared with the Federal Parliament. The houses of the New South Wales Parliament follow the Westminster parliamentary traditions of dress, Green–Red chamber colours and protocols. The houses of the legislature are located in Parliament House on Macquarie Street, Sydney.
