@ Lemina, You make it sound like Australia is over run by spiders Lemina . It really depends were you go however if you stay in the cities and towns you'll most likely never see a spider. Its only when you mindlessly wander into the outback or bushland you may find one but you have a very slim chance too as they usually all hide from things larger then them.
@ Rune, yeah we have bird eating spiders but I have never seen one because they live out in very arid places I've never been outside Queensland so unless I plan to go the Northern Territory or South Australia I will probably never see one.
