Giant Pumice Raft - its a good thing?

There is a giant pumice raft floating towards Queensland Australia, nearly 58 square miles large. Scientists say it came from an underwater volcano near the island of Tonga. The raft should arrive in Australia in about 7 to 12 months. It was first spotted by NASA's Terra satellite on Aug 12.

Michael Hoult and Larissa Brill, passed through this pumice sheet while sailing to Fiji and posted a video on August 17, 2019:

 

This is actually a good thing?

 Scott Bryan, an associate professor at Queensland University of Technology said, during this time the raft of pumice will pick up all sorts of marine life along the way. Things like algae, barnacles, corals, crabs, snails and worms. According to the scientists, these organisms will help rebuild the imperiled Great Barrier Reef. A fresh new wave of immigrants from across the sea.
