Sydney/Adelaide/Port Douglas in December

Hello everybody! My name is Susan. This is the first time I spend my vacation in Australia. I want to see as much as I can in 7 days so I decided to make a tour and visit Sydney, Adelaide and Port Douglas. The slight problem might occur because of the fact that I'm going there in December. I can't possibly get a free week earlier.

Hi, Susan! Your destination is very nice and attractive. Don't be sorry for not being able to use the vacation earlier. The climate in Australia is very pleasant in December and the temperatures are above 20 degrees. However, you can not swim at in the sea and spend your time at the seaside but as I see you want to make a nice tour and visit three beautiful cities in Australia, so you won't have any time for the beach anyway. Sydney is famous for the beautiful Opera House and many bridges. Adelaide is a famous university and shopping centre of the South Australia. Port Douglas is a tropical place in Queensland.
