Coming from farming my guess is 99% of farmers with sheep or cattle would jump at any tag with the right cost and technology balance. Our livestock can be funnelled into a drafting race when they come into for water. With the right tag They could be identified, weighed, and even placed into a holding yard ready to be trucked for sale. all without a person to be seen and with no cost to muster, ie helicopters and time. Given the trend for larger farms with less workforce, any low cost tag with the right tech is a market ready to explode in Australia , imo.
