Alex has had colic too, but is over it now [-o<
We found Mylicon helped (maybe not available in Australia) but I imagine it is similar to other off the shelf wind drops you would find there.
He also had some osteopathic treatment which provided some relief.
We didn't use water but I think its a good idea if you can get her to drink it rather than milk if she's feeding more often than every 3 hours. Just to give her tummy a chance to digest the last feed.
Poor little love, hope she's better soon!
