Observations covering 72 - 231 MHz and Declinations south of $+30^\\circ$ have been performed with the Murchison Widefield Array \"extended\" Phase II configuration over 2018 - 2020 and will be processed to form data products including continuum and polarisation images and mosaics, multi-frequency catalogues, transient search data, and ionospheric measurements. From a pilot field described in this work, we publish an initial data release covering 1,447 sq. deg over 4h < RA < 13h, -32.7deg < Dec < -20.7deg.
