Justine arrives in the bay and cons Marilyn Fisher (Emily Symons) and her stepdaughter, Rebecca out of money by telling them her baby is unwell and she needs a taxi to get to hospital. Aaron, Justine's brother asks her what she is doing in the Bay. It soon becomes apparent Justine is a heroin junkie and she begins stealing from Aaron's guardians Alf (Ray Meagher) and Ailsa Stewart (Judy Nunn). Justine tries to show she is a reformed character by organising a charity event at the surf club with boxer Kostya Tszyu as a guest. However, after the fundraiser, Justine secretly buys some drugs from a dealer. Aaron confronts Justine and accuses her of using, which she denies. Alf and Ailsa's son, Duncan (Lewis Devaney) discovers syringes under Justine's bed and brings one into the dining room, prompting Alf to lose his temper and order Justine to leave. Aaron decides to leave with her and tries to help her by taking away a bag of drugs but when he drops the bag in the diner, he is arrested. Justine then leaves Summer Bay after Aaron refuses to help her.
