In most cases Australian Life Insurers are unwilling to provide income protection for the newly self employed with a history of less than 12 months. Although if you worked as an employ in the same industry then you can apply for a indemnity style income protection benefit. Here is a list of occupations that would qualify for an Indemnity style Income Protection policy.
Backhoe, bobcat, bulldozer or Earthmovers
Mechanic Diesel or Marine
Cook / Chef
Demolition Worker No Explosives
Sheet Metal Worker
Fitter and Turner
Tiler Floors & Walls
House re stumper
Horse Riding Trainer or Instructor
This means that should you claim then you will need to prove your previous 12 months of income. After 12months of trading history you can usually change your policy to an agreed value.
