(Updated 7 Jan 2014) Sea surface temperatures around Australia in 2013 were unusually warm reported the Australian Bureau of Meteorology in it's annual climate statement. Record ocean temperatures were recorded for January and February, with November the second-highest on record. This continues a long term trend for increasing sea surface temperatures around Australia and globally.

Dec 29, 2012: High sea surface temperatures (SST) of up to five degrees above normal are currently being experienced off the north-western Australian coast in a marine heatwave event. Like the extreme marine heatwave event in 2011 this will change marine ecosystems causing coral bleaching and fish mortality and impact on fisheries management and biodiversity.
A similar event occurred over several weeks during the 2010/2011 summer which impacted seafood stocks and marine ecosystems and was associated with an extremely strong La Niña event and a record strength Leeuwin Current down the Western Australian coast.
