Brisbane tuff is a form of welded ignimbrite. It is found in various parts of Brisbane and was quarried extensively in the early history of Brisbane at the Kangaroo Point Cliffs and the (now) Windsor Town Quarry Park for use in construction of Brisbane's earliest buildings.
Brisbane tuff has been used in the construction of the following Brisbane buildings, many of them now heritage-listed:
- Commissariat Store
- Cathedral of St Stephen
- Manor Apartment Hotel
- Old Bishopbourne Chapel (also known as Chapel of the Holy Spirit)
- St Martin's House
- St Mary's Anglican Church, Kangaroo Point
The extent and hardness of Brisbane tuff deposits has often been a barrier to building tunnels in Brisbane due to its 100–150 megapascal strength. However, since 2007, advances in tunnel-boring equipment with tungsten carbide cutting heads has enabled a number of major tunnels to be constructed in Brisbane, e.g. the Clem Jones Tunnel which passes through the Kangaroo Point area.
