It took 4000 kilometres and about two years to get here after being spewed from a volcanic eruption in the Kermadec Islands of New Zealand. Pumice stone washed up on Merimbula and Pambula beach foreshores is believed to be part of the remnants of a raft of porous volcanic rock estimated to be more than 20,000sq km in size from the Havre Seamount volcano.
It is not a new phenomenon with pumice events back in 2007 and then 1984.
Queensland University of Technology researcher Scott Bryan is a world expert in pumice rafts and has been reported in various media outlets on this latest event which has been observed along the coastline from as far north as Rockhampton, Queensland.
Little was known about the seamount until the 2012 Kermadec Islands eruption and resulted in subsequent scientific visits to the site to investigate the seamount.
