Victor Island

  • Victor Island had stable hard coral cover around 30% until TC Debbie in 2017, after which it saw a sharp drop accompanied by a rise in macroalgae. Further losses occurred following the 2020 mass bleaching due to the region-wide accumulated heat stress event.  The most recent surveys show a positive trend in hard coral, a hopeful indication of recovery that will be documented through the semi-annual monitoring program.

  • Presence of disease in the inshore coral communities of Mackay and Hay Point has fluctuated over 13 years of monitoring. Severe bleaching, however, has only been recorded alongside the region-wide accumulated sea surface temperature peak in 2020.
