Sports in Australia are very popular. In many ways Australia
seems to be the sports and outdoor activity capital of the world.
There's a wide range of climates on the continent, so a wide range
of sports activities is available throughout the year.
Surfing is the obvious sport associated with Australia, and if
you are brave enough, you can enjoy this sport all year around.
Swimming is very popular, too. Australians and tourists enjoy
swimming both in swimming pools, and, of course, at a large
number of Australia's beaches. Other popular sports include
walking, jogging, cycling and much more. It may sound
surprising but Australia also offers skiing, cross-country skiing
and snowboarding. The snow in Australia is real and ski resorts
are popular.
Getting back to surfing, it's important to remember that
anyone who wants to get into it should follow the safety rules.
Surfing is a high risk sport, and sharks are not actually the
main danger. Sharks are a common feature of Australian
waters but fatal attacks are rare. Rips put inexperienced
surfers at much greater risk. They are the cause of most
tragedies at beaches.
A rip, or a rip current, is a strong current running out to sea.
It forms not far from the shore. It's difficult to notice when a rip
comes. It drags everything from the beach to sea. Rips are very
dangerous as they can carry a weak or tired swimmer out into
deep water.
To avoid or survive rip currents, surfers and swimmers
should use only life guide protected beaches. They should never
swim or surf alone. They should never enter the surf in places
where swimming is prohibited. Sport is a great way to escape
the stress of modern day living, but it can cause trouble if
people are careless.
