Nick teaches the inorganic/coordination chemistry sections of CHEM2202 (CSR1) in Semester 1 and CHEM1201 (CHEM2) in Semester 2. His course notes will be available on Wattle.
Here are some additional resources that may be helpful:
Chemistry Libretexts (formerly ChemWiki) is a project run by the University of California, Davis. It has a whole bunch of very helpful material on a range of topics. The sections on HSAB theory, crystal field theory and ligand field theory are particularly good.
