Evan Hancock - Sandy Allen

Sandy Allen, played by Catherine Hill, made her first on screen appearance on 5 October 2001. After her husband, John (Adrian Mulraney), learns he has fathered Lolly Allen (Jiordan Anna Tolli) with Cheryl Stark (Caroline Gillmer), he and Sandy come to Erinsborough to meet her. John and Sandy meet with Lolly several times and they are eventually granted full custody of her. A few years later, Lolly (now played by Adelaide Kane) begins fighting with Sandy and John and they decide to let her visit Lou Carpenter (Tom Oliver). When Pepper Steiger (Nicky Whelan) discovers Lolly has some bruising, the teenager reveals she is being abused by Sandy. When her stepmother comes to Ramsay Street, Lolly decides she cannot live with the abuse anymore and sabotages the brakes on Sandy's car. Kane said "It's got to the point where Lolly can't live like this anymore, and this is Lolly's way of dealing with what's been happening. Trying to sabotage her car is a way that Lolly can avoid directly confronting Sandy and actually coming face to face with her because she's so terrified of this horrible woman." Lolly's plan fails and she and Sandy end up having a confrontation by a swimming pool. Sandy becomes aggressive and when she goes to hit Lolly, Lolly pushes her into the pool, where she hits her head. Lolly eventually jumps in and saves Sandy and confesses everything to Lou.

When a DNA test proves John Allen is the biological father of Louise "Lolly" Carpenter, Sandy encourages her husband to meet his daughter. John meets Lolly a few times, before Sandy asks if she can meet her too. John and Sandy meet up with Lolly and Lou Carpenter, the man who thought he was her father, and Sandy gets on well with Lolly. Shortly afterwards, Sandy beings working in a nursery close to Ramsay Street and she annoys Lou by constantly appearing at the local coffee shop. Sandy apologises to Lou and insists their meetings are simply coincidences. John and Sandy eventually apply for full custody of Lolly and they win. Sandy and John then move to the country. Years later Sandy gives birth to two children following IVF. Sandy starts to resent Lolly's presence as she reminds her of John infidelity. She begins abusing Lolly mentally and physically. Lolly returns to Erinsborough and Sandy visits her shortly after, when she hears Lolly ran away. Sandy warns her not to act up again and agrees to look after her, while Lou is away. Lolly later becomes upset and confronts Sandy, while she is cleaning the pool. They have an altercation and Sandy falls into the pool, hitting her head on the way in. Lolly pulls Sandy out and saves her life with CPR. While Sandy is at the hospital, Lolly tells Lou all about the abuse. Upon her return from hospital, Sandy finds her bags packed and she reacts angrily to Lolly's accusations. Lou tells Sandy he has been in contact with John and human services. Sandy leaves realising she has lost her husband and access to her children.
