The Great Outdoors.
Australia is the world’s oldest continent and indigenous Australians have one of the world’s oldest cultures. In Australia you will see unique plants and animals and some of the most beautiful scenery in the world. Many parks have information centres offering advice on where to go, what to see and how to see it – for both your personal safety and to protect our sensitive, natural environment.

Banks and money matters
Banks are generally open between 9.30 – 4.00 pm Monday to Thursday and 9.30 – 5.00 pm on Friday. Foreign currency on traveller’s cheques can be changed at all banks and some of the larger hotels. There are currency exchange facilities including all the international airports.
The Sun
Take care! Our sunlight is very strong and you can get sunburnt. For best sun protection, it is advisable to wear: broad brimmed hat, shirt with collar and sleeves, sun screen with high protection factor.

Swimming
We have so many beautiful places to swim – beaches, lakes, rivers and creeks. Many of our waters are safe for swimming, but if you have any doubts, ask before entering the water. Most of our popular ocean beaches have patrols with lifesaving service. Red and yellow flags marks the area that you are advised to swim within. If there are no flags and no lifeguards on the beach, talk to local people about the best areas to swim.

Staying safe on the roads
Australians drive on the LEFT hand side of the road. For safety, everyone in the car, including children, must wear a seatbelt. Motor cyclists are required to wear a helmet. Watch out for native animals crossing the roads, especially at night. Road signs are erected in places where animals are commonly seen.

Сухая, тихая погода.
(На) улице, ш..гах в п..ти,
Ст..ит, стыдяс.., з..ма (у) входа
И не решается войти.
(Во) л..ду р..ка и мёрзлый тал..ник,
А поперёк, на голый лё..,
Как зерк..ло на подз..ркал..ник,
Поставлен чёрный н..босвод.
Перед ним ст..ит на перекрестке,
Который полузан..сло,
Б..рёза (со) зв..здой
