Hemp Expo (Melbourne), page-12

Don't get me wrong, I do think it's a great idea as Hemp is a great plant I just don't think the Australian Legislation would ever allow a non native species such as Hemp to be used in such a massive way due to the general rule being to restore the area to there native ecosystems. I know you said a mop plant but it would still be an expensive endeavor to get Hemp approved for this use and imo focusing on other areas of the business would be more economical at this stage.
