Emerald Botanic Gardens.

To the west of Emerald is an area known as The Gemfields, with small towns such as Sapphire and Rubyvale indicating the type of gems found there.
The sapphire fields located there are the largest in the southern hemisphere.

The above photo is a 'free caravan/motorhome' park for self-contained ones.  We didn't do that.
