Again, why don't you consider self-representing?
The disruption to a child's time with their parent is the one contravention the Court does take seriously, so I'm inclined to disagree with the 'nothing you can do' suggestions above. Your situation doesn't sound terribly complicated - you're meant to see the child, she refuses to facilitate that time in breach of the orders. Unless you're ordered to pay for half the school fees, that issue shouldn't be an influencing factor at all. The police won't do anything because it's out of their jurisdiction, but you, on the other hand, can and should look at filing an application for contravention orders.
It's simple enough. Look back on every weekend you were meant to have the child. List the first weekend as the first contravention, list the second weekend as the second contravention, and so on and so forth up until the present. Show how you've tried to resolve the matter amicably, show how all attempts have been refused.
Ask the Court to impose a bond upon her to encourage her to revert to the orders, and if she breaches the bond by contravening the orders again, then the Court is going to consider taking more drastic action if you have to file contravention proceedings over the same issue.
