The Sun is very strong in Australia. There are signs and posters on buses and buildings warning about the high skin cancer rate in Australia. Fortunately Liz always wears sunblock and brings plenty of it. She made sure I wore sunblock 100 and stayed protected. I also made sure to wear a hat to protect my face, head and ears. After all of our walking and relaxing in the sun, neither of us got a sunburn.
The water has some strong currents and a rip tide is always possible. Be careful when swimming especially if you are alone. There are life guards on the beach but they can't keep an eye on everyone so be proactive in your personal safety.
Jelly Fish are dangerous and some have no known cure for their sting. The Lifesavers post warning when jellyfish are spotted in the water. Head their caution and stay out of harms way until the jellyfish clear. You don't want the pain of a jellyfish sting or the potential life threatening reactions the venom can cause.
Just a note on how the water can be destrcutive:
On 6 February 1938, 5 people drowned and over 250 people were rescued after a series of large waves struck the beach and pulled people back into the sea, a day that became known as "Black Sunday". This event is still remembered today and memorials are in the area. Unbelievable to think such a beautiful beach was the sight of such tragedy and destruction. Nature is a powerful beast.
There are high waves some days so watch out! Maybe the waves are not the most dangerous, but all the surf boards flying around in the water is! (I met a girl who'd got her teeth knocked out!)
