Rose help
I'm keeping my fingers crossed this isn't fireblight on my banksia rose, but any ideas what it could be?

Found this on a website, would have put a link in but not sure how to do it.
Peeling bark is cause for alarm if you don't know what causes it. Bark is like a plant's skin and protects the inside tissue from injury, infection and moisture loss. There are several layers of bark on a rose just as we have several layer of epidermis. The loss of the top layer is not a cause for concern, but if bark peeling goes into the cambium, serious loss of vigour or even death can occur.
Variety
There is one variety of rose that is bred to have peeling bark. Lady Banks Rose is a yellow climbing rose that has sloughing bark that adds an ornamental appeal to the plant. The top layer of the bark peels off in long sheets and leaves the trunk with a rustic, interesting appearance that persists in winter long after the flowers and leaves are gone. The older stems have the greatest amount of peeling while the young stems retain the bark until it changes colour.
Canker
A fungus called Coniothyrium wernsdorfiae is the source of many bark problems. It attacks the green bark which turns reddish brown and gets purplish black lesions that split and peel the bark. The fungus spreads down the stem and even into the main trunk. Any infected tissue collapses and dies. The infected canes must be removed back to fresh, healthy wood. Use a sanitising spray when making the cuts to prevent spreading the disease. Another fungus called Coniothyrium fuckelii is also responsible for swollen bark that ruptures and peels. It is treated the same way.
Thanks yvisstevis for the feed back, I've since looked up fire blight and in all the pictures the foliage is brown and dying, the foliage on the banksia rose look ok so still not sure what is going on.
Really I've never heard this but will be highly delighted if that is the case, think I will do a bit of research on lady banks.
Just been looking on line and it certainly looks like it could be a natural thing with this rose, thank you so much for pointing me in the right direction.
