Henry Parkes, often referred to as the 'Father of Federation', delivered a notable oration in Tenterfield that stirred the colonies of Australia towards discussing the need for federation. The speech took place at the Tenterfield School of Arts, a site that became a landmark in this pivotal moment of Australian history. In his address, Parkes called for a national parliament and a united Australia, arguing that the colonies were too small and isolated to manage effectively on their own. He emphasized the importance of collaborating on defense, trade, and development issues faced by all colonies.

Parkes highlighted the successes and needs of New South Wales as a precursor to a more unified approach among the colonies, suggesting that a federal system would enhance stability and prosperity. His passionate presentation resonated with many, drawing considerable media coverage and public interest. Following the oration, it became clear that the idea of Australian federation had gained momentum, leading to several constitutional conventions in the following years.

The gathering at Tenterfield marked a significant shift in the political landscape of Australia, expanding the conversation about federation beyond the political elites and into public discourse. Parkes' speech set the stage for further debates and discussions that ultimately culminated in the formation of the Commonwealth of Australia in 1901, uniting the six self-governing colonies into a single nation.
