We report spectroscopic classification by OzDES of supernovae discovered by the Dark Energy Survey (ATel #4668). 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 classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), details of which are reported in the table below.

(1) Best match to the over-luminous SN 1999aa, consistent with 91T-like classification reported by M. Smith et al. (ATel #5548).

(2) Good matches to SN 1999ef at +105, SN 1990B at +72, and SN 1990aa at +116 days.
