A. David Malouf

D. Jack Davis
E. Judith Wright
Choose the correct answer from the options given below:

The correct option is B, C, D only.

To understand why this option is correct, we can look at the background and contributions of each writer listed in the question:

1. Kevin Gilbert (B): An influential Aboriginal activist, poet, playwright, and printmaker. He wrote the groundbreaking book Because White Man'll Never Do It (1973) and the play The Cherry Pickers (1968), widely recognized as the first written play by an Aboriginal writer. He was a key figure in establishing the Aboriginal Tent Embassy in 1972 and campaigned vigorously for Aboriginal rights and sovereignty.

2. Oodgeroo Noonuccal (C): Formerly known as Kath Walker, she was a pioneering Indigenous Australian poet, political activist, artist, and educator. Her collection We Are Going (1964) was the first book of poetry published by an Aboriginal Australian, making her a seminal figure in Aboriginal literature. She was also a leading advocate for the landmark 1967 referendum that granted constitutional recognition to Indigenous Australians.

3. Jack Davis (D): A renowned Aboriginal playwright, poet, and activist. His plays, such as No Sugar and The Dreamers, dramatically portrayed the historical and ongoing struggles of Indigenous Australians. Through his writing and leadership, Davis played a crucial role in bringing Aboriginal stories and voices to the mainstream Australian cultural landscape.

Why the other writers are excluded:
- David Malouf (A): A celebrated Australian novelist and poet of Lebanese and English descent. He is not an Aboriginal writer and did not pioneer the Aboriginal movement.
- Judith Wright (E): A highly respected non-Indigenous Australian poet and environmentalist. While she was a passionate supporter of Aboriginal land rights and worked closely with Indigenous activists (including Oodgeroo Noonuccal), she herself was not an Indigenous pioneer of the movement.

Therefore, the writers who pioneered the Australian Aboriginal Movement among the given options are Kevin Gilbert, Oodgeroo Noonuccal, and Jack Davis.
