This dude surprised me with his braveness doing this... (he's 5!!). This swing rope is very high and he did so well! you can't see him but Bryce is in the water waiting to catch him and was counting him down so he knew when to let go (I guess what I'm trying to say is this was done under the most controlled conditions possible!).
This swimming hole is part of Gardners Falls - about 55 mins drive north of Coolum, Sunshine Coast. This is one of two swing ropes (the other is MUCH higher) and hole itself is fairly deep. On this trip we also saw a turtle sun bathing on the rocks and a whip snake slithering along next to the track... so tread carefully!
