Rental Bond Refund Data

I am currently looking for data related to the portion of rental bonds that are refunded to a tenant on a postcode-by-postcode basis.

The purpose of acquiring the data is to identify suburbs where tenants are being taken advantage of by their landlords or property managers.

If you can provide a similar dataset to the one provided by the NSW government, https://www.fairtrading.nsw.gov.au/about-fair-trading/data-and-statistics/rental-bond-data

many thanks Josh
