     Australia is famous for its beautiful beaches. And Australian people love swimming and going to the beach.

But it wasn't always that way.

     Different Climate, Different Habits

     When Europeans first invaded Australia, the only people here who were good at swimming were the

Aboriginal people. The Europeans came from climates where it was too cold to swim. However the warm

climate of Australia soon changed their attitude to swimming. At first, only men swam. They swam without

any clothes on-there were no women to see them.

     Cover up!

     By the 1880 and 1890s visiting the beach was very fashionable. People wore everyday street clothes-much

more than people wear at the beach today.

     In those days people believed they should cover their most body so it would not be seen by the opposite

sex. Special bathing costumes were designed for women. This costumes used a lot of cloth and were very

heavy when wet, making it difficult to swim.

     Laws Made and Laws Changed

     The government decided to stop men swimming naked. It passed a law which forbade bathing between 6

am and 7 am. But in 1903, the laws changed; people could swim in the daytime, but they had to wear

neck-to-knee costumes.

     The Shrinking Costume

     As time passed, swimming costumes became smaller and more convenient.

     At first men and women were covered from neck to knee. Then arms became bare. Then more of the legs

were uncovered. Each new change was regarded by many as shocking and rude and people wrote letters to

the newspapers complaining about the new costume. Nowadays some people go to special"nude beaches" to

swim naked.

      However, most people cover their bodies more than they did ten years ago-not because they think bare

skin is shocking-but to protect their skin from the harmful rays of the sun.
