If a family member sponsors you you still need to have the trade buttessed by one of the buttessing bodies as the Aussie Sponsored-Designated Area Sponsored-State Sponsored Visas are part of the Send immigration route.......
Good News though... "Dental Technician" (3492-15) is on the Send Occupations List (SOL) & is a 60 pt occupation (good news). It is a trade that is buttessed by the TRA.
The Australian Bureau of Statistics hold all the standards of job descriptions (www.abs.gov.au) and hold the following as your hubbies job description:
Constructs and repairs dentures and other dental devices.
Skill Level: The entry requirement for this occupation is an AQF Diploma or higher qualification or at least 3 years relevant experience. In some instances relevant experience is required in addition to the formal qualification. Registration or licensing is required.
Tasks Include: receives and interprets written orders from dentists fabricates full and partial dentures constructs metal clasps, inlays, bridgework and other aids repairs, makes additions or relines denture bases constructs maxillofacial appliances
I would have a read of all the documentation for buttessment in your documentation at www.immi.gov.au as you may very well qualify for a send independent visa rather than a sponsored one.
I would also contact an immigration agent for advice off-forum. We used George Lombard at www.austimmigration.com.au & I can 110% rec'd him & his team. Others to consider include Go Matilda, OE Visas, etc. Doing a search of the forum for AGENT will give you lots of invaluable information about them.
