Why did Victoria separate from New South Wales in 1851?

The separation of Victoria from New South Wales in 1851 was primarily driven by the dissatisfaction of settlers in the Port Phillip District.

These settlers, particularly pastoralists, agitated for independence due to two main grievances:

• Inadequate Representation: They felt they lacked sufficient voice and representation within the New South Wales Legislative Council.12
• Fiscal Resentment: They strongly resented that local revenues generated in the Port Phillip District were being channeled toward the New South Wales area rather than being invested in their own development.2

In response to these demands, the British Parliament passed the Australian Colonies Government Act, which took effect on July 1, 1851. This legislation formally established Victoria as a separate colony, granting it its own Legislative Council and moving the region toward self-government.123
