I would ask your agent to enquire of the ACT Government for a Nomination -
http://www.business.act.gov.au/servi...lled_migration
Or maybe telephone them yourself? T +61 2 6207 1957.
I had a couple of clients with IT skills obtain Nominations; there are a number of Federal Departments in the ACT and I think there is more likely to be a need for someone with your wife's skills there than in most if not all of the other States and Territories.
Hope this helps, and good luck!
