@cara - Yes, I read that too, when I was trying to find the program again. Thanks for your response!
But this is a very recent interview with someone who is basing a business on this, his name:
Adrian Spencer, AgriFutures Australia Researcher of the Year 11.04.22
P.S. I was thinking that I had heard that the kelp in Tasmania has been affected by global warming, but he is obviously working off a different area. In the interview he was talking about an area 3 times larger than the Barrier Reef off the Queensland Coast
I am pretty excited about these projects and will subscribe to a publication by the Australian Seaweed Institute
