Baiame is the male creation figure in the Dreaming traditions of several southeastern Australian Aboriginal peoples. He is often described as a creator and sky father, but the stories differ among the communities who know him.
Baiame is associated with peoples including the Wonnarua, Kamilaroi, Guringay, Eora, Darkinjung and Wiradjuri. In versions of his story, he comes from the sky, creates features such as rivers, mountains and forests, and gives people laws, ceremonies, songs and cultural knowledge. He is also linked with the establishment of an initiation site.
Baiame should not be treated as a single universally shared Aboriginal deity. Aboriginal Australia contains hundreds of distinct cultural and language groups, each with its own traditions and names. The other options belong to different regional traditions: Bunjil is a major creator figure for several peoples in southeastern Victoria, while Ngurunderi and Daramulum are associated with other specific story cycles. Baiame is the answer for the southeastern traditions identified in the question.
