Recent experimental results on hadronic tau decays into strange particles by the OPAL Collaboration are employed to determine V-us and m(s) from moments of the invariant mass distribution. Our results are V-us=0.2208+/-0.0034 and m(s)(2 GeV)=81+/-22 MeV. The error on V-us is dominated by experiment and should be improvable in the future. Nevertheless, already now our result is competitive with the standard extraction of V-us from K-e3 decays, and it is compatible with unitarity.
