Known as Ayers rock before being returned to its traditional owners, the rock is made of grey/red arkose 347.3m tall & 8.85km in circumference.

Lake Eyre is Australia's largest salt lake, situated in the driest region of the country. When dry which is its usual state , the lake bed is a glistening sheet of white salt.
The lake itself was named after Edward John Eyre who in 1840 became the first European to sight it.
To the East and North East of the lake lie three of the country hottest and driest deserts. Water winds its way through these deserts through a network of channels but the majority of water is lost to evaporation and absorption along the way.
When the lake does fill up which has only been on three occasions in the 20th century, it becomes temporally Australia's largest lake.
The Sydney Harbour Bridge: Weighing 52800 tonnes, with an arch span of 503m the bridge was opened in 1932. It is one of the longest one-bow bridges in the world with a length of 1 150m. The bridge is just 66 cm shorter than the Golden Gate Bridge in San Francisco. Over 200 000 cars cross the bridge per day, paying a toll of $2 each. Approx 80,000 litres of paint are required for each coat, enough to cover an area equivalent to 60 soccer fields. Paul Hogan (from the movie Crocodile Dundee) used to work on the Sydney Harbour Bridge as a painter.
