Delurking to post this link to an earlier study by the same guy (same name and institute, at least) in which he found that the bones of vegans and non-vegans had identical density:

Also of interest, one of the
founding bodies of the Garvan Institute is CRC for Innovative Dairy Products.
Quote from the earlier study:
“Bone health in vegetarians, particularly vegans, has been a concern for some time, because as a group they tend to have a lower protein and calcium intake than the population at large.”
“In this work we showed that although the vegans studied do indeed have lower protein and calcium intakes, their bone density is virtually identical to that of people who eat a wide variety of foods, including animal protein.”
Edited to add link.
