Utilities aren't included.
From Veda:
What is repayment history information?
Repayment history information is whether the minimum repayment on a credit account, like a credit card, personal loan or mortgage has been made on time (or within a 5 day grace period) and if not, how late the payment was made, for a particular month. Only licensed credit providers can share and receive repayment history information. This doesn?t include telco and utility companies. Repayment history information is recorded monthly and can be held on your credit report for 2 years.
Utilities and Telco bills
are included in the new credit reform system in the sense that if you are more than 60 days overdue on a utility or telco bill and the debt is $150 or more, the utility/telco can/may provide this information to credit reporting agencies as a default and it will stay on your credit file for 5 years.
Not only for PPOR,
For investors with IPs, this could be fixed water charges, sewerage or water consumption charges in IP owner's name.
Quote from Veda here:
Can paying my phone or electricity bill late impact my credit file?
Yes, it can. Under the Privacy Act 1988, an overdue debt can be listed on your consumer credit report when it is overdue by 60 days or more, when the debt is at least $150. Please note that information about whether your have paid your account on time or not cannot be listed by a telco or utility provider as they are not a licensed credit providers, unless you are 60 days or more overdue.
Before listing a default, the credit provider has sent a written notice seeking payment of the overdue debt and a written notice stating that the default may be listed with a credit reporting body.
Once you've paid the overdue debt, the credit provider is required to update the listing on your credit report as soon as is practicable.
If the overdue debt is classified as a serious credit infringement, where you have left or appear to have left your last known address, the credit provider must first have listed a default and must have had no contact with you for the preceding 6 months.
The legislation does not place obligations on credit providers with respect to commercial credit defaults which means the obligations relating to consumer defaults and serious credit infringements does not apply to commercial defaults and clearouts.
