Nicola, skilled visas are processed according to priority groups set by the Department of Immigration. First are the employer-sponsored visas, then state-sponsored, then applications where the occupation is listed in Schedule 1 of the new SOL, then everyone else.
As your husband is a teacher and your application is family sponsored, I think you may be in processing group 4 which means at least 18 months processing. Have a look at http://www.immi.gov.au/about/charters/client-services-charter/visas/8.0.htm.
