Oddeus: You get some paralysing bacteria from them. And they are active over the whole year.
Yes, the ticks here are nasty and can paralyse and kill pets, but they aren't around all year, mainly during the warmer seasons and they aren't in all states.
And then there's the mosquitos that give you Ross River Virus, which I've contracted and is debilitating (no treatment either) and Barmah Forest virus.
Good thing is we don't have rabies, yet.
infinite9: Also, is it true you can still get carp herpes from falling into a river or creek?
No, you can't catch it like that.
Although you may contract carp herpes if you have sexual relations with them, carp felatio.
