My sister has gapped it interstate

We helped her out of a DV situation, got her out of emergency housing and into our home as she’s pregnant. He was released on bail and she is fighting the police putting a no contact order on him. She’s left our place and gone interstate as confirmed by toll charges in a car we have been paying for that she’s driving(Tasmania we believe). All her belongings are here(we are talking a room full of furniture and clothes and baby items) she’s refusing contact with any of the family, what do we do with it? Do I have to keep it if she’s not responding?
