Your wife is well within her rights to move to wherever she likes, mate. Sorry. Moving away, although inconsiderate, does not break the order as the onus is on you to make arrangements to see your daughter. However, if your ex-wife has actually said that you are no longer allowed to see your daughter then she is contravening the contact order. I'm afraid that the implications of this will only amount to your ex being reminded of the terms of the order and to make the time available for you to have the agreed contact.
All the best mate.
