News Corp's The Australian [theaustralian.com.au] (archived copy [webcitation.org]) reports that
Cyclone Debbie is expected to disrupt up to $US3.2 billion ([A]$4.2 [billion]) worth of Queensland coking coal exports and rob customers in Asia of access to premium coal for five weeks as landslides shut down the [Goonyella] railway system that moves half the state’s coal exports.
Coke made from the coal is used for making steel in India, South Korea and Japan.
