When we did our top end adventure (Pilbara to Cairns) and spent a while in Cairns, we were having a meal a restraunt somewhere in Cairns and right above our heads in the roof beams there was one of those monster orb spiders ... I mean MONSTER !!!! it must have had a body easily 12" long and I became transfixed by it's stare , my wife freaked out when she saw it
, we wound up moving to another table and I could not help but keep looking at the 8 legged beast.
It was the stuff of night mares ....
I hear they eat frogs and lizards and small snakes too.
If they behave anything like the one's we get in the mangroves locally here , if there is one , there will be dozen of them , they hang out in colonies , the biggest I've encountered here is had a body about 2" long and their webs are very strong and super sticky too ....
In summer it pays to have a torch or to carry a strick out in front of you when walking down the foot here too.
