Record rainfall triggering dangerous flooding in Australia is prompting another warning from officials: beware of wayward reptiles -- such as crocodiles and snakes.

Nearly four feet of rain has fallen across parts of Northeast Australia in the span of a week, forcing officials to open floodgates at a dam near the coastal city of Townsville to prevent a river from overflowing.

The Australian Army has been deployed to deliver over 70,000 sandbags and rescue residents from their rooftops from the "unprecedented" flooding, Sky News reported.

Government officials on Monday warned that floodwaters could also contain crocodiles and snakes, since the animals may move around in search of a "quiet place."

“Crocodiles may be seen crossing roads, and when flooding recedes, crocodiles can turn up in unusual places such as farm dams or waterholes where they have not been seen before," Queensland Minister for Environment Leeanne Enoch said in a statement. “Similarly, snakes are very good swimmers and they too may turn up unexpectedly."

An Australian woman posted a photo on Facebook of a crocodile outside her father’s house in Mundingburra, located outside of Townsville.

"Cannot stress it enough to stay out of the water," she wrote.

Australia's Bureau of Meteorology said that heavy rain could continue in the region until Thursday, and some areas could expect more than a year's worth of rain before conditions ease.
