Lots ..... it even gets to a point where you are glad you have one type of poisonous snake in your neighborhood.

Where I live to the North West of Sydney, you get either red Belly Black snakes or Brown snakes (we have such descriptive names) - you never get both though. If you have the shy and slightly less poisonous red belly black in your area you are happy because it means they have chased out the more aggressive and very poisonous Brown's.

Both can kill you, but the red will move away if disturbed whereas the Brown will defend.
