The Last Anniversary is a six‑part Australian comedy‑drama set on the fictional Scribbly Gum Island, where journalist Sophie Honeywell (Teresa Palmer) inherits a house from her ex‑boyfriend’s great‑aunt and stumbles into long‑buried family secrets tied to a decades‑old disappearance. Packed with dry humour, intergenerational tension and psychological intrigue, the stellar ensemble cast—including Miranda Richardson, Danielle Macdonald and Helen Thomson—brings Moriarty’s tale of motherhood, mystery and family legacy richly to life.
