9,469 I read recently, but thats probably not accurate, as I don't know how reliable the source was!

It is a minimum of c. 2000 miles, but it is meaningless to want a specific measurement more detailed than that because the coastline of any island is a quasi-fractal shape, whose length varies according to the level of resolution you look at it.  It could be 5,000 or 10,000 or 15,000 miles if you want it to be.
