The disappearance of Katie Walker near a Sydney beach has taken a new turn as her father says evidence from her apartment points to plans to return to the UK, not to vanish. Police have said Walker may have walked into the ocean, but her family argues that her final days appear far more complicated.

According to details uncovered by her father, Walker, 46, was facing mounting pressure before she went missing. She had reportedly lost nearly $200,000, her bank accounts were frozen, her phone was not working properly, and her visa was close to expiring. Those setbacks have fueled questions about her state of mind and about who she may have been in contact with at the time.

Her father has spent months retracing her movements and says what was left behind in the apartment suggests she was preparing to travel back to Britain. He also believes a still-unidentified man could be central to understanding what happened, raising the possibility that someone may know more than has been revealed publicly.

The case now sits at the center of competing explanations: the official view that Walker entered the water, and her family’s belief that the full story has not yet emerged. With financial troubles, communication problems and unanswered questions about people around her, the mystery surrounding her disappearance remains unresolved.
