The Cepheid period-luminosity relation is the primary distance indicator used in most determinations of the Hubble constant. The tip of the red giant branch (TRGB) is an alternative basis. Using the new Australian National University (ANU) SkyMapper Telescope, we calibrate the Tully-Fisher relation in the I band. We find that the TRGB and Cepheid distance scales are consistent.
