The property matters have nothing to do with the parenting matters and the court on friday will not discuss the parenting matter.
Of there is no date listed before the hearing of the parenting matter in mid july, you wait.
If she files nothing then on the hearing date you seek for the matter to proceed on what the court has before it.
If she files late you ask the court to strike out what she has filed because it was out of time.
It is up to the court to decide what it does.
If she wants to file an amended response then you can seek an order for costs for what you have done if you have had legal representation as the hearing cannot go ahead on the set date.
The property orders made cannot simply be varied and the courts do not change thins easily unless they can see that there was non disclosure and a party has not complied with the act.
If Friday is for property that is all the court will only deal with that.
Is there anything else I can assist you with?
