I used to catch them in my backyard, and remove them from neighbours yards, quite regularly. Extremely placid, you can tap them on the nose with out any problem (not that I recommend this with any species of snake!)
Eric Worrell was bitten once by a large specimen many many years ago, and suffered quite badly from it. But from what I understand, bites are very rare. For such an innoffensive little creature, it's a real shame the number that succumb to cats and shovels each year.
