No there are no court orders
To offer you a better insight.
You would not be in contravention of any orders if you were not to consult the mother, as, like I said, the 'common law' definition of parental responsibility applies.
However, if you were to just up and leave, without at least informing the mother, and the mother does then make an application to one of the Federal Family Courts (a factor you could not be certain of in spite of her present absence), then leaving without consultation
could be frowned upon. A crafty lawyer could also twist the circumstances back on to you
Further,
if the mother were to make an application to the Court, as with the legislative definition of ESPR (equal shared parental responsibility) as defined in the Act, that would then come into play, so too would the legislative pathway the Court must follow. This includes the primary considerations, one of them being
' the right of the child to a meaningful relationship with both of his/her parents'.
The absence of a parent in and of itself will not negate the Courts responsibility to look at all of the facts of the case and to follow the legislative pathway.
Always better to have more information than less when we are talking about children and uncertainties (of the Court and other parent) in my view. Keep up the good work looking after your child on your own!
