Taipan is a million galaxy southern hemisphere redshift survey currently in commissioning on the UKST telescope at SSO. Goals are a 1% measurement of the Hubble Constant from baryon acoustic oscillations and a ten times increase in the galaxy mapping within redshift 0.25 and its resultant dark matter map from fundamental plane peculiar velocities.
OzDES is observing redshifts for Dark Energy Survey, aiming to place 2500 galaxies on the SNIa Hubble diagram. At its halfway point on the AAT we have 22,000 redshifts of SNIa hosts down to r = 24. A reverberation mapping sample of AGN is following 800 objects. Stacked spectra are telling us about the stellar populations of SNIa hosts.
