Will they make it?

Queen Jennifer has a CBR250RR (she will graduate to a Kwaka one day) and has had the same set of Sportmax Alpha-12H tyres on it for the last year but cannot tell me how many kilometres she has done on them.
They have just hit the wear marker in the centre of the rear, still have about 2mm of tread there and I need to know if you know if they will last a trip from Newcastle, NSW to Melbourne, Vic.
We will be travelling via every twisty road we can find and I am not sure whether I should get new rubber now, find a store in Melbourne or if she'll make it all the way home.
If I had to put money on it I would say she will make it as a 250 will not shred a tyre like a bigger bike can but I would like a 2nd opinion as I am not 100% sure.
If you know, please let me know.
If you do not, read and find out what people post.
