In mid February 1930 the second expedition quickly returned to their Mountain Base and on across the mountains to the junction of the Yuat with the Baiyer and Jimmi Rivers. They prospected south along the Baiyer River to its junction with the Maramuni and Tarua Rivers, where they established a palisaded forward camp naming the place 'Akmana Junction.' From this base they prospected along the Maramuni River and its tributaries, again without success. Finally they prospected the Tarua River south past the tributary which flows to Waipai, once more without success and on the advice of mining engineer Seale, it was decided there was nothing to justify further exploration. They had not progressed to any country on the southern watershed through which the early explorers and prospectors travelled to the Hagan Range and Wabag. The party returned to Madang, sailing for Sydney on 3 July 1930.
