Alternatives to down and synthetic sleeping bags?

Hi all
I'm have a dilemma in finding a sleeping bag I feel comfortable purchasing. I'm vegan and won't purchase anything using down. On the other hand, I'm predominantly vegan for environmental reasons, so I'm also not too keen on purchasing a synthetic sleeping bag either (i.e. plastics/micro-plastics).
Are there any alternatives to these two options? Maybe a small aussie business that creates sleeping bag fill from a nature material or something? Done some research and searched through this group to no avail.
Any recommendations would be amazing. Cheers!
