MTNS (Mathematical Theory of Networks and Systems) 2012 conference. I stay in Trinity College in the University of Melbourne.
Trinity College is founded in 1872 as the first residential college of the University of Melbourne. It is very old but quite beautiful. The accommodation is also nice; old but comfortable, not so expensive, and safe. The internet access works very well.
The University of Melbourne is founded in 1853, and Melbourne School of Engineering in 1861, the oldest engineering faculty in Australia (in 2011 it celebrates 150 years of engineering education at the University of Melbourne.
