I should think they'd hope so.Anyway sea levels are set to rise not drop, so that continent of theirs is only going to stay submerged.
Judging by that map, if it turned into dry land, they'd be within spitting distance of Brisbane

Incidentally, the west of Scotland is rising by as much as 1 millimetre a year, still bouncing back after the last ice age.
But SE England, especially London, is sinking.
