The rain event smashing NSW is so large it has been described as "hard to fathom". But one statistic puts the scale in terms that are easier to understand, albeit mind-blowing.
The BBC's weather team put together a simple graphic that aired to audiences on Monday.
It showed that between Friday last week and Monday Sydney had been smashed by 733mm of rain.
In contrast, London - perceived as a rainy city - records just 615mm annually.
