Results are presented from searches for massive boson resonances with decay modes $X\to$ $Z\gamma$ and $X^{\pm}\to$ $W^{\pm}\gamma$ using 13 TeV proton-proton collision data collected by the ATLAS detector at the LHC in 2015 and 2016. For the $Z\gamma$ channel, a high $E_T$ lepton trigger selects events where the Z boson is detected from decays to $e^+e^-$ and $\mu^+\mu^-$. These data are used to search for resonances with mass between 250 GeV and 2.4 TeV. The search is extended to higher X mass in the $X\to$ $Z\gamma$ and $X^{\pm}\to$ $W^{\pm}\gamma$ channels using hadronic decays of the W/Z bosons. The events are selected using a high $E_T$ photon trigger with a boosted Z/W boson reconstructed from merged di-jet clusters in a large radius jet. The data are used to search for resonances $X\to$ $Z\gamma$ with spins 0 and 2 and $X^{\pm}\to$ $W^{\pm}\gamma$ with spin 1.
