Flights have been cancelled and a number of airports closed as two major storms hit Australia.
Tropical Cyclone Marcia has hit the Queensland coast between St Lawrence and Yeppoon.
Initially a Category Five storm, it has now been downgraded to a Three but warnings are still in place for heavy rain and abnormally high tides.
Qantas says it has cancelled 26 flights between Rockhampton, Gladstone, Hervey Bay, Townsville, Bundaberg, Mackay and Hamilton Island due to Marcia.
Its website said: "Weather conditions associated with Tropical Cyclone Marcia are likely to disrupt the travel arrangements for a number of Qantas customers travelling to/from Brisbane, Hamilton Island, Rockhampton, Mackay, Gladstone, Hervey Bay, Bundaberg, Coolangatta, Biloela, Blackall, Barcaldine, Longreach and Wellcamp.
"Options are available to Qantas customers holding a valid ticket issued on/before 19 February for travel on/before 24 February 2015 who are affected by Tropical Cyclone Marcia."
Jetstar has issued a statement saying flights to and from Brisbane, Gold Coast, Sunshine Coast, Mackay and Hamilton Island are most likely to be affected.
Virgin has cancelled all of its flights in and out of Bundaberg, Gladstone, Hervey Bay, Mackay and Rockhampton and has urged customers to check their flight status.
