The incident is a reminder regarding the dangers of driving through floodwaters.
The Department of Fire and Emergency Services provides the following advice:
Never walk or drive through floodwaters. Driving through flood waters is very dangerous as floodwaters can be very powerful – just a small amount of flood water can wash your vehicle away.
You also cannot see what lies beneath flooded roads, with large sections often washed away, or hazardous items floating in the water, creating dangerous conditions.
