The ATLAS experiment at the Large Hadron Collider (LHC) has been able to
collect 5.25 fb-1 of data in 2011. For many physics analyses both in context of
the Standard Model (SM) and Beyond the Standard Model (BSM) theories such as
Higgs boson searches, tau leptons play an important role. Thus, triggering on
hadronic tau decays is an essential ingredient for the success of those
measurements. This contribution will summarize the developed efforts to meet
this challenge. Efficiency measurements using data taken in 2011 at a
center-of-mass energy of 7 TeV are described and results are presented. An
outlook on further developments of the tau trigger algorithms, to match future
requirements and higher instantaneous luminosities are summarised in the end.
