In the large mass region, the dominant decay mode of the Higgs boson is to two W bosons, where the Higgs can be produced via either gluon fusion or vector boson fusion. Of the possible W decay modes, the current analyses focus on the W(->l nu)W(->l nu) decay channels where the lepton is either an electron or muon. At a center of mass energy of 7 TeV, the results from the ATLAS detector are combined for each of the three modes ee, e mu, or mu mu, in order to maximise the signal sensitivity. We investigate the possible sensitivity gained in including a single hadronic tau channel (W->tau nu->(tau_had nu) nu) in this analysis, and discuss the method in comparison to the standard H->WW->l nu l nu search. Our work currently focuses on the hadronic tau identification and understanding the jet -> tau fake rate.
