Four million people are in the firing line of Cyclone Alfred. It's expected to hit between the Sunshine Coast and the Gold Coast - a stretch of Australia known for its beautiful beaches and top surf – as well as Brisbane, Australia's third-biggest city.

Conditions are intensifying across the south-east Queensland and northern NSW coast, with the Bureau of Meteorology warning Tropical Cyclone Alfred's slow track will bring a "very high risk of significant impacts".

Australians are bracing for Cyclone Alfred, as its first effects are felt. The slow-moving storm is expected to reach the coast of Southeast Queensland and northeastern New South Wales tonight or early tomorrow morning.
