Australia car insurance dispute: can AFCA review a denied claim?

Yes, in many cases. AFCA says it can consider complaints about denial of car insurance claims, delays in settlement, assessed loss values, disputes about liability and excess, and some other insurance issues. You can complain directly to AFCA or first ask the insurer to review the decision through its internal dispute-resolution process. Official source: AFCA.
