Database mistakes on entry happen in Torrens. Rarer, but not unheard of. Tasmanian "owned" and lived on block for decades, when sold found they'd owned the one next door. There's a critical role in acceptance where somebody as agent has to say yay or nay and a Queensland couple had the agent say the wrong outcome when the real owner didn't consent and it went to the high court if I recall.

Torrens is great but CAP theory still applies.
