To begin with, the Australian Mathematics Society Bulletin publishes "Abstracts of Ph.D. Theses":

The BULLETIN of the Australian
Mathematical Society publishes
Abstracts of Australasian Ph.D.
Theses. The abstract submitted to the
BULLETIN may be the abstract included
in the thesis itself. However, the
BULLETIN will accept abstracts of up
to three pages, which may include
references. All the mathematical
sciences are covered, including pure
and applied mathematics, probability
and mathematical statistics,
mathematical physics, and mathematical
computer science.
