Coober Pedy.

Day 9.
On Tuesday we went on a bus tour. It was also Nanny's birthday. We went swimming in the morning.
On the bus tour we went to an underground mine tour and in the underground mine there was a movie theatre. We saw a lot of opal. The bus driver showed us the dynamite they used.
I bought the A opal necklace. We got to see the big big rocks. On the way back to there we saw lots of cool things. We saw a big big rock that looks like a camel. We also saw the underground church and the church has lots of things in it.
We also saw the dog fence. It keeps the dogs away from the sheep. The dog fence is over 5000km long.
We also saw some moon rocks. They used the place for Mad Max 3 Beyond Thunderdome and Escape the Red Planet.
