Sun we just relaxed and then headed to The Strand. Its a strand of beach. Here I saw a stinger enclosurer in the sea. They netted it off protecting the swimmers from marine stingers. They have 2 such ones along the beach. You are advised to swim within this net. They also did up a rock pool. Kissing Point rock pool. 
They bulit a breakwaters around the pool. This whole stretch was attacked by the Japanese during WWII.
There is of course no 100 percent gurantee that the stingers can't get into these protected pools. But I did see alot of people swimming.
Its still very hot. Townsville has 320 days of sunshine and sometimes they don't even have winter. You got wear sunblock and sunglasses when stepping out. Ok I got to go back to my book. Tata!
