What are the other basic principles behind child parenting arrangements?

When making a parenting arrangement, Australian family laws says that there are three basic principles that need to be considered:

1.The parents should share the parenting responsibilities equally
2.The parents should try and make parenting arrangements without going to court
3.The parents are both responsible for the child until the child is 18 years old

These principles may not always able to be applied in every circumstance, especially when there is a question over the child’s safety. All decisions should be made in the best interests of the child.
