Hi Adam,
Great question! Dawul Wuru currently don’t grow any bush tucker, it is a future goal for them, so we don’t have any information for you in that regard. I’d recommend researching different types of bush tucker which can be grown in Far North Queensland, and making some assumptions based on that. For example, you could suggest different plants which could be grown and identify their water needs.
I’ve had a quick look on google and have found these two documents which should be a good starting point for you:

Bush Tucker for North Qld
I hope that helps, please let me know if you have any other questions!
