The Higgs boson decays to bosons provide very detailed measurements of Higgs boson properties and interactions, and shine light on the mechanism of electroweak symmetry breaking. This paper presents the latest measurements of the Higgs boson coupling properties performed by the ATLAS experiment in various bosonic decay channels (WW*, ZZ* and γγ) using the full Run-2 p-p collision dataset collected at $\sqrt{s}$=13 TeV with luminosity of 139 fb$^{-1}$. Results on production mode cross sections, Simplified Template Cross Sections (STXS), and their interpretations are presented. Specific scenarios of physics beyond the Standard Model are tested, as well as generic extensions within the framework of the Standard Model Effective Field Theory (SMEFT).
