Generally, E. acmenoides, E. melliodora, E. moluccana, or E. rummeryi, all of the family Myrtaceae
I have only found images of this Australian wood as a burl but because it is rarely available in the USA I have not made much of a search, so would not be at all surprized if it is available in lumber form in Australia. Although I list the name form with no space, it is more commonly shown as "yellow box".
