Northern Australia

Northern Australia often refers to the following. While it may be slightly ambiguous, as a general rule of thumb, it never goes south of -21°, although it's typically used to describe the tropics of Australia. It is characterised by warm and humid temperatures, often around 30°C all year around. Often the summer months are often rainy and hence called "wet season", while the winter months are usually called "dry season".

Stay safe
Some parts of Northern Australia, particularly in Queensland and the Northern Territory are colloquially called croc country – due to the large number of crocodiles in the region, particularly closer to the coastlines. Stay at least 100 metres from rivers and estuaries, unless you would like to end up being a croc's dinner.
