It really bad news to here about this, but I think if you are carrying camera you should keep it in bag, when you need it or want to click a picture you can take it out from your bag and try to walk on road side. I think this tip will help.
Hi,
I am planing to go Sydney. I have found some very nice tips from your post. I think it is very good idea that luggage should be lite weight. Thanks for sharing this, When I'll come from Sydney I'll definitely share my experience with you.:)
