Having trouble getting next IP loan due to my type of employment

Hi guys

Hoping I can get some help.  My husband and I are currently using a broker to obtain a loan for a second IP.  However, my employment becomes an issue when assessing our lending criteria.  I have been contracting for the last two years (I am a qualified accountant).  Basically I take contracts for various amounts of time through employment agencies, ie the last three contracts I've had have been 9 months, 9 months and now 4 months.  It is full time work and I am paid direct by the employment agency.  The banks don't seem to like this.  In particular at the moment as they cannot see what I will be doing after 4 months time, although I know I will pick up another contract.  I have worked in the same industry for ten years.  Everything else is fine, we have enough of deposit, no bad credit history, current property values we own are good and husbands employment is fine he has been in the same job for the last ten years.  At present we tried ANZ as they had some sort of loan which specified contract accountants ok to apply, but no luck, even though my income and tax returns show high income.  Any ideas how to approach this or banks people know of that could assist us?  Is there another way to list me on the loan with my husband being the main income earner and putting me down as extra wages part time?

Thanks in advance for your help.
