The ATLAS experiment can measure consistent proton collisions at the highest energies to date with $\sqrt{s}=13.6$ TeV. This allows many previously impossible measurements of standard model physics and searches for new physics. This talk presents the recent results of searches for high mass heavy neutral leptons using the run 2 dataset and explores the possibility of future measurements with extended HNL models. These models can lead to exotic signals in the detector. HNLs and the Weinberg Operator are given new limits into the TeV scale in electron and muon mixing channels.
