This species is widespread in the lowlands of Papua New Guinea, including satellite islands, and in northern and north-east Australia. Subspecies G. m. hypoxantha (formerly treated as a separate species) is endemic to the twin-islands of Biak-Supiori in Geelvink Bay, Papua (formerly Irian Jaya), Indonesia. There are very few historical records of this form (Mayr and Meyer de Schauensee 1939), and just four subsequent records: three records at Warafri, eastern Biak, in 1991-1994 (Gibbs 1993, P. Gregory, I. and R. Burrows in litt. 1994, N. Bostock in litt. 1999) and several records in and around Biak-Utara Reserve in 1997 (S. van Balen in litt. 2000). It was not recorded during three visits to the islands during the 1980s (K. D. Bishop in litt. 1987), nor three visits during the 1990s (Poulsen and Frolander 1994, Eastwood 1996b, M. Van Beirs in litt. 2000).
