Most of us are familiar with hemp clothing, and some of us have tried eating hemp seeds with yoghurt or blending them into smoothies.
It's been hailed as a superfood that can even be used to replace plastic, so hemp seems like an obvious crop for Australian farmers to embrace.

Canada is the world's leading producer, exporting hemp seeds, oil and protein powder. And China is not far behind.
But in Australia, production is limited and struggling to keep pace.
