Malmquist bias corrections to galaxy distances depend sensitively on the underlying density field from which the distance-indicator population is assumed to have been drawn. In most previous studies of large-scale streaming motions, the density field has been assumed to be homogeneous. In this paper, inhomogeneous Malmquist bias corrections are calculated using the density field of optical galaxies within |8000 \ km \ s^-1|. For E and S0 galaxies in the Great Attractor region, the strong outward streaming in the foreground of the Great Attractor is not significantly affected by these new corrections. Some evidence of backside infall into the Great Attractor had previously been claimed by Dressler & Faber on the basis of the homogeneously corrected |D ₍-| peculiar velocities. It is found here that approximately |500 \ km \ s^-1| of their backside infall is due to inappropriate homogeneous Malmquist bias corrections. The best-fitting flow model to the inhomogeneously corrected |D ₍-| peculiar velocities in the CMB frame is a Great Attractor-centred infall of |266 51 \ km \ s^-1| at the Local Group plus a bulk dipole motion of |212 82 \ km \ s^-1| towards |l=316^, b=10^|.
