Many theories of physics beyond the Standards Model (BSM) predict the existence of vector-like quarks (VLQs) - coloured fermions whose left- and right-handed components transform equally under the Standard Model gauge groups. VLQs with masses near the TeV scale can provide a natural solution to the hierarchy problem by stabilising the mass of the Higgs boson. In this talk, I will review some recent results from the ATLAS experiment on searches for vector-like quarks that couple preferentially to the third generation. I will discuss reinterpretations of some of these searches for other BSM production processes and conclude with some perspectives on future VLQ searches in light of the current results.
