Sydneysiders have been warned drivers to take extra care on the road this morning.

Melbourne was treated to its own stunning display of fog last week which also obscured the city’s skyline.

People on flights this morning have been advised to contact their airline, with delays estimated at up to two hours.

This morning’s fog has lifted, but some domestic services affected. Please check with your airline for information on flights.
