Australia, by Clàudia Pascual

The capital city of Australia is Canberra but the biggest city is Sydney.

The Murray River is the longest river in Australia. It's about 2.520 kilometres long.

Mount Kosciuszko, in New South Wales, is the highest mountain in Australia. It is about 2.228 metres high.

I think the most amazing construction is the Sydney Opera House. It is one of the world's most distinctive 20th century buildings.
