in reply to all. Common sense needs to apply. Yes we have spiders and snakes (including the most poisonous in the world), that if you are really unlucky or in the wrong place at the right time can give you a nasty bite. In the cities and the burbs you are unlikey to encounter them, but it does happen. If you must leave footwear outside, then of course you should shake it out before wearing, and never place your hand where you can't see it. The majority of snakes will sense you coming and be long gone before you reach them, if by chance you walk up on one sunning itself just back off slowly, no sudden movement, don't panic, you will only get bitten if you cause the snake grief i.e. you cut off it's escape route or you step on it, this is only likely to occur in the bush or rain forests, again common sense, keep your eyes open. If do you get bitten then try and remember what it looked like and remain calm and have someone go for help, we have anti-venom for virtually every bite you could get in Australia.
Enjoy your trip !!!!!!!
