Question

What discovery caused the creation of new Australian towns?

Answer 1

Gold.

Explanation:

The discovery of gold in Australia occurred intermittently in the early 19th century. The Australian gold rushes, beginning in 1851, were accompanied by a huge population explosion from an influx of immigrants. Like in the Californian Gold Rush, the Australian gold rushes were the key factor in booming towns and sprouting of new ones. Australian convict colonies become into more progressive cities. Finally, the gold rushes may have been a factor in an exploration of the interior of the continent.
