A CNN article about the floods in Queensland says:
To make matters worse for the terrified residents fleeing their homes, there have been numerous sightings of crocodiles and snakes being swept along with the floodwaters, 9 News reported.
Mundingburra resident Erin Hahn told the broadcaster she spotted a freshwater crocodile in front of her father's house Sunday night.
"(It) was nearly a meter or two long (3.3 to 6.6 feet)," she said.

It isn't true that only the US doesn't use the metric system - there are also Myanmar and Liberia.
