When did New South Wales gain representative government?

New South Wales gained representative government in 1842.1

While a small Legislative Council consisting of government officials and nominated colonists had been established earlier in 1823, it did not provide representative government. The 1842 reform introduced a legislature of 36 members, 24 of whom were elected, though this body still held limited powers.1

It was not until 1856 that the colony transitioned to responsible government, establishing a new legislature with a Legislative Council and a wholly elected Legislative Assembly, which shifted executive power from the governor to political leaders with majority support.1
