What kind of orders are they? Consent or parenting orders?
In short, yes, you can breach a parenting order, but there may be repercussions for doing so. The other parent may file for contravention and you will be brought to court. If the judge decides that your decision to breach the order was an unreasonable action, then you may be issued a penalty or, in more serious cases, have the child's time with you reduced.
I always suggest attempting to sort issues out via mediation with the other party before jumping to conclusions and breaching orders. Of you can give me an idea of what kind of orders they are, or a little more information about the situation, I might be able to provide more guidance.
