The second data release of European Space Agency's Gaia mission (DR2) in April 2018 provided measurements of the positions, motions and photometric properties for more than one billion stars. This data is unprecedented both in its quantity and its accuracy, and covers a large volume of the Milky Way. Gaia DR2 in combination with ground-based spectroscopic surveys has already revolutionised our view of the Galactic disc and halo in a variety of ways, including finding new stellar streams, discovering the impact of satellite galaxies on the disc, and enhancing our understanding of the interplay between the disc and halo. The Gaia collaboration will release improved astrometry and photometry data in Q3 of 2020 as Early DR3 (EDR3). In order for our community to be prepared for Gaia EDR3, this Specialist Discussion Meeting will give an overview of what has been learned about the Galactic disc and halo from Gaia DR2, and discuss how we can further enhance our knowledge of the Galactic disc and halo with Gaia EDR3.
