To enhance the idea of a powerful vehicle traversing the outback, the musical approach was to develop a thematic "call of the wild" vocal hook (chant), building a piece of music around it coloured with tribal-like textures/rhythms, and grandiose orchestral flourishes.

There was a challenge in keeping the tribal, more contemporary palette of instruments at the start and end of the film consistent with the orchestral section in the middle, whilst also addressing three distinct moments in the story. However, the elements were woven together in a way that eventuated a piece with a sense of cohesiveness throughout.
