Studies cited for the 2008 wreck analysis concluded that Sydney's torpedo and shell damage left her unable to survive more than about four and a half hours once the sea reached state four. The rapid final sinking then caused intact, air-filled compartments to implode under external pressure. The explanation remains a hypothesis: surviving sailors may have believed they could control the damage and therefore remained aboard instead of abandoning ship early. The ship was their best life raft, while fire, destroyed command spaces, damaged boats, and heavy casualties complicated any organized evacuation. Fragmented boats in the debris field could have been damaged during the violent sinking rather than proving that every escape craft was unusable beforehand. Worsening sea conditions may then have overtaken the repair effort and left no time to get clear. This rejects conspiracy claims while preserving the uncertainty created by the absence of Australian witnesses.

A cautious explanation for Sydney's lack of survivors
The wreck evidence suggests Sydney could remain afloat only briefly in worsening seas, supporting a cautious hypothesis that survivors stayed aboard fighting to save the ship until escape became impossible.
