While Australia's west faces the threat of bushfires, in New South Wales it's a very different story.

Heavy rain and showers are set to drench Sydney for another week as the city wades through its wettest start to December in 20 years, the Sydney Morning Herald reported.

Weather experts say the downpour would continue today and tomorrow before breaking up at the weekend. The threat of wet weather will remain until at least next Wednesday.

More than 40 millimetres of rain fell on the city centre yesterday.
