I hadn't picked up the difference. The Department's
Map clearly identifies
World Heritage Area (Land) in the legend which includes the Palm Islands. The
Location/Boundary Plan is harder to read but you can still make out that the Palm islands are within the inscribed area.
Its seems clear from the GBRMPA
zoning plans that most islands are not zoned (coloured), suggesting they are not within the park boundary. This makes sense since its a Marine Park and its worth noting that a number of islands within the inscribed area have their own National Park designation (e.g.
Whitsunday Islands National Park,
Magnetic Island National Park and
Orpheus Island National Park which is part of the Palm Islands). Looks like Orpheus Island has a handful of inhabitants
URL. Its interesting to see in the Palm Island wiki link that "There is no freehold land title on Palm Island, with property owned by either the Local or State Government", however Greater Palm Island is not a designated National Park, probably more down to politics than anything else.
So looks like the two connections are goers. Makes up for my proposed Mossman Gorge community which isn't technically within the Wet Tropics boundary although clearly surrounded on three sides by rainforest!
