Very precocious, small to intermediate tree producing fruit with high kernel recovery and attractive kernels. Origin: Hidden Valley Plantations, Beerwah, Queensland, Australia, by H. Bell and D. Bell. Renown (Macadamia integrifolia) × Own Choice (M. tetraphylla), as determined with genetic markers; crossed 1976; selected 1980; introd. 1988; Australian PBR 88/001, 1988.
