In The Messenger 192 a short report was published on the ESO–SKAO workshop Coordinated Surveys of the Southern Sky, which was held at ESO in Garching in early 2023. An important goal of this workshop was to publish a collection of articles that describe in some detail what existing synergetic science would be possible with well-planned coordinated surveys using ESO and SKAO facilities. The other four articles in this edition of The Messenger, covering respectively the Galaxy, galaxy formation and evolution, cosmology, and the epoch of reionisation and cosmic dawn, present such synergies and promising ways forward, and serve as references for ESO–SKAO coordinated surveys. By way of introduction, this article describes the SKAO and SKA precursor/pathfinder facilities and also briefly highlights the current and future ESO instrumentation that will be of particular importance for such coordinated surveys of the southern sky.
