DATA SOURCES

Where our information comes from

Clear sources help you make informed decisions. Here’s where our information comes from and how we use it.

Suburbs, postcodes and councils
Suburb and locality boundaries, council boundaries and postal areas come from the Australian Bureau of Statistics. They are published under a Creative Commons Attribution 4.0 licence.
We match suburb and council boundaries to identify the relevant council. If the match is unclear, we leave it blank.
Business registration details
We use ABN Lookup data from the Australian Business Register to check business registrations and help prevent duplicate listings. This data is published under a Creative Commons Attribution 3.0 Australia licence.
We don’t display ABNs on public listings. A registration check confirms registration details; it doesn’t assess the quality of a business’s work.
Rebates, deadlines and scheme rules
We source rebate amounts, key dates and eligibility rules from official government pages and link them so you can check the details.
Schemes can change or close. If we can no longer confirm information is current, we remove it until it can be checked.
Licences and accreditations
Licence and accreditation details are supplied by businesses. We link to the relevant official registers so you can check their claims directly.
We don’t issue licences or accreditations. The relevant authority is the source for confirming a business’s status.
