While the half-sisters once shared a close bond, Allegra claims she and Cassandra have become estranged in the time since their father Max’s death in October 2018.  

Daily Mail Australia has reached out to Cassandra Thorburn for comment. 

It comes after Cassandra spoke candidly about the ‘grief’ of her marriage breakdown during the first episode of her podcast, Divorce Story: Surviving Separation.

Speaking to psychologist Jackie Manning, Cassandra revealed: ‘People often say, are you over them? Yes I am over them.

‘I am over my ex-husband but it is about going through the grief of going through a divorce. Going through a divorce is really stressful, so that is something to grieve.’

She added: ‘Divorce is a trauma, it is something you have to go through a process of. You can’t underestimate that someone going through grief has to go through a process and if they have had a trauma.’ 

Karl and Cassandra share three children, Jackson, 20, River, 12, and Ava, 14. 

Karl is expecting his first child, a daughter, with wife Jasmine in May.
