Margo Lanagan has been announced as winner of two awards at this year's World Fantasy Convention held in Madison, Wisconsin, over the weekend.
She was announced as winner in the Short Fiction category for "Singing My Sister Down", and in the Collection catgeory for Black Juice.
I'd have to check but I believe this is the first time an Australian author has won a World Fantasy Award.
See Locus Magazine for a full list of results.
[Update: I was incorrect in stating that Margo was the first Australian winner of a World Fantasy Award, Shaun Tan won for Best Artist in 2001, and Jack Dann and Janeen Webb won for Best Anthology in 1999 with Dreaming Down Under. My apologies.]
