Geography

Mount Gambier is built on the slopes of a volcano of the same name. This volcano is considered dormant. The area is known for its volcanic features, including:

  • Blue Lake: This is a large crater lake that is the city's main water source. It is famous for its color, which changes from a dark steel-grey in the winter to a bright, brilliant blue in the summer. The traditional owners of the land, the Bungandidj people, call the lake "Waawor".
  • Umpherston Sinkhole: This is a collapsed cave that has been turned into a beautiful sunken garden. It is a popular tourist attraction where you can see possums and other animals. It is also known as "Balumbul" in the local Indigenous language.
  • Other Caves and Sinkholes: The region has many other limestone caves and sinkholes that are popular with visitors and cave divers.

History

The area was first seen by a British explorer in 1800. The city itself was founded in 1854. It was first called "Gambier Town" and was named after Admiral James Gambier.
