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.

Tropical Cyclone Alfred's centre is expected to hit Australia on Friday night or Saturday morning, with impacts already being felt across south-east Queensland and northern NSW. The category two system was expected to remain of similar intensity until the centre started to interact with the coast and islands.

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".
