Its existance is only possible due to particular climate conditions that affect an area of the world where no other land rises even remotely near sea level.

Yeah, right in the middle of a warm current. And it's so unique - I mean, we don't have any other examples of an area at higher latitudes being warmed by an ocean current. Other than Europe. Oh, yeah, and we can't forget Bermuda - and gee, Bermuda has coral reefs also.

So much for the uniqueness part of your statement.

You also have one wrong comment too (at least in the interpretation of what I said about how unique Lord Howe is) here :
right in the middle of a warm current. And it's so unique - I mean, we don't have any other examples of an area at higher latitudes being warmed by an ocean current. Other than Europe. Oh, yeah, and we can't forget Bermuda - and gee, Bermuda has coral reefs also.

I think I was clearly referring to the Southwestern Pacific, since I said that there's no land rising from the ocean until Port Macquarie, NSW.
What you point out is true - besides Lord Howe there are only two other high latitude coral reefs : Bermuda (Northern Atlantic) and northern Red Sea (until Eilat, Israel).
BTW, considering the diffence of temperature for subtropical latitudes between the Northern (much warmer) and souhtern hemisphere, also in this point, like in any other, Lord Howe Island is the superlative
