We identified discrete importation events of the <i>mcr-1</i> gene on incompatibility group IncI2 plasmids in <i>Escherichia coli</i> isolated from patients in New South Wales, Australia, in 2011 and 2013. <i>mcr-1</i> is present in a small minority of colistin-resistant Enterobacteriaceae and appears not to be established locally.
