We report new spectroscopic classifications by OzDES of supernovae discovered by the Dark Energy Survey. The spectra (370-885nm) were obtained with the AAOmega Spectrograph (Saunders et al. 2004, SPIE, 5492, 389) and the 2dF fibre positioner at the Anglo-Australian Telescope (AAT). Object classification was performed using superfit (Howell and Wang, 2002, BAAS, 34, 1256) and SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), the details of which are reported in the table below.

1. Previously classified as an SNII in ATel #
6591. Has since developed clear He absorption features, and is a very good match to 1993J. r=20.7 on 20141130.
