We report spectroscopic classification of optical transients with the Wide Field Spectrograph (WiFeS - Dopita et al., 2007, ApSS, 310, 255) on the ANU 2.3m telescope at Siding Spring Observatory, NSW Australia, using the B3000/R3000 gratings (3500-9800 A, 1 A resolution). Discovery and classification information are found in the table below, targets were observed on 2014 Mar 04, classifications were made with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). PSN J12104022-3403407 exhibits classical SN Ia spectral features about three weeks after maximum - Ca NIR in absorption, Si 6355 with adjacent Fe lines, with most line profiles becoming dominated by emission. TCP J19445890-1451183 in Barnard's Galaxy (NGC 6822) is a classical nova, with broad Balmer lines (Ha, Hb, Hg) in emission.
