Justine Welles is a fictional character from the Australian soap opera Home and Away, played by Bree Desborough.

"[1] In 1999, Justine was accused of murdering Ruby Collins (Brittany Jones; Sian Tierney), a young child.

[3] Desborough told Jason Herbision of Inside Soap that she was really excited to read the script and said it was a strong storyline to be working on.

[5] Desborough said Justine was set to run away, but Rebecca Nash's (Belinda Emmett) attitude changes her plans.

"[5] Justine stands trial for Ruby's murder and the prosecution focuses on her failure to report the bruising she found on the baby.

"[7] 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.

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.

Everyone tells her he is bad news but Justine refuses to take it on board until Danny attacks Sam Marshall (Ryan Clark).

Justine then causes problems at home by encouraging foster sister, Tiegan Brook (Sally Marrett) to shoplift, landing her in trouble.

After Pippa leaves to be with Ian, Rebecca and her husband, Travis Nash (Nic Testoni) move into Summer Bay house and assume responsibility for Justine, Tiegan and Sam.

Justine later breaks up with Vinnie when she falls for Tom (Graeme Squires) during rehearsals for a Year 11 production of Romeo and Juliet.

Justine takes a job babysitting for Steve (Don Halbert) and Wendy Collins (Jayne Leslie), looking after their baby daughter, Ruby.

The director, Curt Bacon (Michael Rowan) spends plenty of time rehearsing with Justine and anticipates a forthcoming scene where she is required to be naked.
