The 12 apostles of Jesus Christ, who lived around the 1st century, are all deceased today. According to Christian tradition and historical records, all of the original 12 apostles except for John were martyred, meaning they died as martyrs for their faith. John is traditionally believed to have lived to an old age and died of natural causes sometime after AD 98. Thus, none of the original 12 apostles are still alive today in the physical sense.

If the question refers instead to the "12 Apostles" as a famous natural rock formation on the Great Ocean Road in Australia, only seven of the original twelve rock stacks remain due to erosion, while there are now about 30 rock formations altogether along that coast.

Please clarify if the interest is related to the historical apostles or the natural landmark.
