We report the detection of two new extra-solar planets from the Anglo-Australian Planet Search around the stars HD142 and HD23079. The planet orbiting HD142 has an orbital period of just under one year, while that orbiting HD23079 has a period of just under two years. HD142 falls into the class of "eccentric" gas giants. HD23079 lies in the recently uncovered class of "epsilon Ret-like" planets - extra-solar gas giant planets with near-circular orbits outside 0.1 a.u. The recent discovery of several more members of this class provides new impetus for the extension of existing planet searches to longer periods, in the search for Jupiter-like planets in Jupiter-like orbits.
