Abstract:	We present sensitive SCUBA 450 um and 850 um continuum imaging observations of the inner 2'.3 (2.8 kpc) of NGC 5128 (Centaurus A) and large-scale 850 um of the dust lane in the galaxy, up to 5'.7 (6.8 kpc) in extend. The 850 um continuum emission of Centarus A shows a high surface-brightness band across the core, similar to the optical dust lane (courtesy AAO) and submillimetre observations by Hawarden et al. 1993 and Mirabel et al. 1999, and for the first time also reveal low surface-brightness regions extending farther north and south of the optical dust lane. The observations are interpreted in the context of model predictions of a morphology determined by a warped dust disk (Nicholson, Bland-Hawthorne & Taylor 1992; Quillen, Graham & Frogel 1993).
