The appropriate information can be found on the Department of Immigration and Citizenship site, specifically http://www.immi.gov.au/skilled/skilled-workers/sbs/ Relevant section seems to be under Processing Arrangements. Here it says "If you have applied for a visa, do not make arrangements to move to Australia. Do not leave your employment, sell your home or book travel arrangements until you are advised in writing that you have been granted a visa." Probably not what anyone wantas to hear, sorry!
