To help tighten constraints on stellar and Galactic evolution models, we present the largest high-resolution analysis of Li abundances A(Li) to date, with results for over 100 000 GALAH field stars spanning effective temperatures $5900\\,\\mathrm{K} \\lesssim \\rm{T_{eff}} \\lesssim7000\\,\\mathrm{K}$ and metallicities $-3 \\lesssim \\rm[Fe/H] \\lesssim +0.5$. We separated these stars into two groups, on the warm and cool side of the so-called Li-dip, a localised region of the Kiel diagram wherein lithium is severely depleted.
