Susie McAllister was a corrupt Real Estate Agent who came to Summer Bay in February 2021. Although she was supposedly hoping to sell some houses, she had bigger plans for her own bank balance. She began to date John Palmer (even though she didn't fancy him) and convinced him to organise a surf competition. Afterwards, she stole the proceeds from that. Worse still, she ripped off Leah Patterson and Justin Morgan to the tune of $90,000. The pair were hoping to buy their first home and turned to Susie for help. She was almost caught by Irene who was suspicious of her. She knocked out Irene with a rag soaked in chloroform and skipped town.
Her body was later found and some of Summer Bay's residents came under suspicion for her murder. High up on the list were Justin and John for obvious reasons. Her murderer was later revealed to be Stephen Tennyson.
Susie was played by Bridie Carter.
