In international news, it is believed two Australians have died as a result of two small sightseeing planes colliding mid-air off the coast of Alaska.

Across the two seaplanes were 14 passengers, four of whom have been confirmed dead and two missing, including an Australian, who were travelling on a seven-day cruise ship tour from Vancouver to Anchorage.

Rescuers say the planes were partially submerged upside down in the seawater after crashing on a steep section of rocky shoreline.
