The creation of the Legislative Assembly in 1856 was a turning point in Australian democracy, introducing the bicameral parliamentary system that would later be adopted by other Australian parliaments.

It met for the first time on 22 May 1856 in the original chamber built in 1843. The Legislative Assembly continues to meet in the oldest legislative chamber in Australia.

Significant conservation work was recently completed in 2023.

The Members’ benches were restored with the replacement of deteriorated leather. Thousands of custom-made buttons were commissioned for the project, and worn carpet was replaced with historically authentic materials.

Significant furniture such as the Speaker’s Chair and chamber table were conserved, with upholstery replaced, varnish stripped back and French polishing applied.

Decorative stencilling and gilding were applied by hand and rendering, plaster and paintwork was restored.

Functional requirements were addressed with extensive upgrades to the lighting, air-conditioning, and technology services.

To provide accessibility to wheelchair users, alterations were made to the original chamber table and doors within the chamber were automated.

The Legislative Chamber Restoration Project won the Interiors and Objects category of the 2024 NSW National Trust Awards, recognising the best practice conservation and celebrating all people involved.
