It is now possible to observationally identify and characterise galaxies within the first billion years of the Universe, over a wide range of luminosities and environments, via deep near-IR imaging and ALMA's ground-breaking sub-mm observations. In the next decade, as we enter the era of LOFAR, SKA, JWST, and 30-40m class telescopes, direct observations are will continue to be extended in both look-back time sensitivity. In order to interpret and benchmark these breakthrough studies, we continue to advance our knowledge of nearby, low-redshift analogues to primordial galaxies, where we can conduct detailed explorations of star-formation in chemically pristine and extreme environments. In this meeting we will showcase our current understanding of galaxies in the high-redshift Universe, and discuss analogue systems and their potential in providing insight into early galaxy formation.
