IDR aims to contact you with a decision within 15 business days of receiving your complaint. We may contact you for additional information and agree a reasonable alternative timeframe.

If your complaint isn’t resolved within 45 days, you can refer it to the Financial Ombudsman Service (FOS) Australia, as per step 3, even if we’re still considering it.

Seek review by an external service

We expect our procedures will deal fairly and promptly with your complaint.
However, if you remain dissatisfied you can refer your complaint to the Financial Ombudsman Service (FOS) Australia – a free, independent external dispute resolution scheme.

An FOS Australia determination is binding on us, provided you accept the determination. If you don’t, you have the option of seeking remedies elsewhere.

FOS Australia is available to customers who fall within their terms of reference and they’ll advise if they can help you.
