Does it need evidence to cancel consent order?
or they just cancel it with no evidence of the allegations.
If I read your initial post correctly, the kids have already been included in an interim order?
Regardless, yes all state & territory courts having jurisdiction can act under section 68R of the family law act to revive, vary, discharge or suspend existing parenting orders (in relation to who a named child may spend time with).
The court can do so on it's own fruition, or by the application of any person. There need only be allegations that satisfy a magistrate that an interim order including kids is justified, at least until a proper hearing where some evidence to support allegations would be expected..
I recommend you take advice from
@Rod or a solicitor of your choosing regarding an application to vary ASAP.
