Gaia EDR3 offers greatly improved kinematics for nearby objects, includingmembers of nearby young stellar moving groups (NYMGs). In this study, we aim toidentify low-mass NYMG members (spectral types of M0 to mid-L) in Gaia EDR3. Wecalculated spatio-kinematic membership probabilities utilising a Bayesianmembership probability calculation scheme developed in our previous study. Weevaluated stellar youth primarily based on colour-magnitude diagram positions.Combining spatio-kinematic membership assessment and youth evaluation, weidentified ~2900 low-mass NYMG candidate members including ~700 previouslyclaimed members. In the set of ~2200 new candidate members, ~550 appear to beyoung based on NUV brightness. Our pilot spectroscopic study with WiFeS on theANU 2.3-m telescope observed 78 candidates, with 79 per cent confirmed asmembers. Using our new member sample, we estimated an isochronal age of thebeta-Pictoris Moving Group. The mean age (~10 Myr), which is around half theage of recent estimates, suggests either a truly younger age of thebeta-Pictoris Moving Group or inaccuracies in contemporary isochrones. As themain results of this study, we provide lists of newly confirmed and candidatelow-mass NYMG members.
