Sunscreen is a must!
While the Australian environment is unpredictable, sunscreen is a must-have for everyone. Even if you enjoy getting a tan, don't do it without wearing plenty of sunscreen because Australia's sun is extremely intense.
With a weaker ozone layer, Australia not only heats up quickly, but the rays are also very damaging to your skin, to the point that you may feel your skin searing. The blister will be painful and the sunburn will remain for weeks.
Put on a shirt, apply sunscreen, and wear a hat to keep safe. It also has to be done in that order. If you have really pale skin, a hat and a sundress or shirt may be necessary to keep that area covered. This is definitely one of the top things about Australia You Should Know before traveling to this country.
