That review provided its findings to the then Federal Environment Minister Greg Hunt in December 2015.
In September 2016 the Turnbull Coalition Government commenced a further public consultation process to develop new management plans for the marine parks in order to change the zoning.
In March 2018 the revised management plans were tabled in the Australian Parliament for consideration.
Changes to the original 2012 zoning in the parks included removal of almost half the high level protective green ‘sanctuary’ zoning across the network - an area almost twice the size of the state of Victoria and equivalent in area to the loss of half of Australia's national parks on land - the biggest single windback of conservation area in Australia's history.
In 2014 the Abbott Coalition Government suspended the parks from operation pending a review.
