I would not want to crowd one nor tease it with food, but we never hear of injuries with the local crocs. There have been reports of Pacific crocs (swimming in a pond at night) and Belize while spearfishing, but that's all I know of.
Talk with the golfers that have hit balls close to the ponds back when it was open - at least two I know of biten.
On the mainland, at least a few times a year there's people killed
