I was extremely pleased with https://www.hatsbythe100.com.au/collections/akubra-hats for current styles, perhaps you could reach out to them.
Thank you I did . Apparently the CEO is not available now . Damn shame loved that hat .I can only hope to find one for sale somewhere or if they go into production again
Viberg - Service Boot® 2030 BCT - Whiskey Dip Dye Shell Cordovan - $1,544 The timeless design and rugged durability of the Service Boot® are synonymous with the Viberg brand and have been since 1931. This model is crafted using genuine Horween shell cordovan leather. 
AURALEE - Pleated cotton-blend tweed trousers - $535 Auralee’s exacting approach to suiting is evidenced by these grey trousers, cut from a soft blend of cotton, wool and cashmere tweed. 
Spier & MacKay - Dark Olive - Wool Tweed Overshirt - $198.00 Featuring soft yet sturdy wool tweed, our overshirts make the perfect layering piece for mild Fall weather. 
I have not seen the Fern Green felt colour but I betcha a custom hatter could find a felt in a similar colour and make you a new one.
Akubra still carries the color just doesn't make the CEO anymore .
