For a free DIY reverse address lookup in Australia, you'll need to use AU financial information databases and Google.com.au as an investigative tool.
This is how you can find out who an AU address belongs to for free.
Furthermore, a free DIY reverse mailing address lookup is really your only option for real results. Unfortunately, paid address lookup services will offer you only a little help.
This can make an AU reverse address lookup seem like a daunting task. There are many online address research services on the internet that promise results for a small fee.
However, many of these Australian reverse address lookup services are simply clickbait scams or are just trying to extract a small fee from you. They will not be able to provide the AU address information you are looking for.
A DIY reverse address search will almost always be the best option.
Free Australian Reverse Address Search
So, is a free DIY reverse address lookup even possible in Australia?
Yes, but it will require a research effort on your part
Thankfully, many AU addresses in the modern age are available publicly, they are just surrounded by a lot of other data which makes the task of a reverse address lookup a little difficult.
By available publicly, we mean that they are available on the internet. So, how do you begin to perform a correct Australia reverse address lookup?
By free reverse address lookup methods
This is done by utilizing Google.com.au and financial databases. These are just a couple of ways for you to do your own Australian reverse address search if you are new to on-line researching.
However, if the reverse address lookup is important to you, we recommend that you use a professional.
Free Australia Reverse Address Lookup Summary
Use the Google.com.au Search Operator: "Exact Phrase Match."
Search the AU address in financial databases.
Google.com.au Reverse Address Search
Google.com.au is typically where you should start when beginning an AU reverse address search. This is a great way to start an address research task when it is combined with "Google.com.au Search Operators."
This also answers the common question: "how do I do a reverse address lookup for free on Google.com.au?"
The answer is using Google.com.au Search Operators
Search Operators are special text characters and commands that greatly extend the capabilities of a regular Google.com.au search. The one specific Google Search Operators that works well with an address is quotes ("").
This Operator (Exact Phrase Match) searches Google.com.au for 100% the exact phrase that is being searched within the quotes. If an Australia address is searched inside quotes, only results containing that address will appear.
This will get rid of a near infinite amount of unwanted similar AU address that will not help in the reverse address lookup.
Unfortunately, you'll need to search multiple variations of the AU address due to the fact that there is not a uniform structure to how addresses are displayed.

You'll know what we are talking about when we say Australian addresses are not uniform if we give you an example. An address such as 09-123 Fake Street can be displayed as,
9 123 Fake St
9-123 Fake St
09 123 Fake St
09-123 Fake St
9 123 Fake Street
09 123 Fake Street
9-123 Fake Street
09-123 Fake Street
Unit 9 123 Fake Street
Unit #9 123 Fake Street
123 Fake Street (9)
and many more variations.
You can see why an Exact Phrase Match would not work well on a full AU address. To solve this issue you can search the address in Exact Phrase Match chunks:
"123 Fake Street" "State" or "123" "Fake St" "State."
As for the unit number, just don't include it. If you are doing an Exact Phrase Match on an address, you'll be given only a few results. This will be easy to go through. A unit number will be an unnecessary wild card that will throw your results off.
AU Address Databases
After you're finished your Google.com.au research, you can move onto AU financial databases. Unfortunately, these are usually not free but are often just asking for a small fee.
Many Australians have mortgages on their property. If they have a mortgage, they will often have what's called a "lien." We could go more in-depth on what a lien is, but it's basically collateral on your loan. A person's lien is typically available publicly.
Then there are Australian property records. If you know the exact AU address, you can lookup the property records.
The method of keeping property records changes based on AU jurisdictions
This means you'll have to do a little digging to find out how to get these records based on your government jurisdiction.
Now, it should be obvious to you why Australia paid address lookup services cannot be used. These AU reverse address lookup services are almost always disingenuous and if they can get information on an Australian address, it will be fragmented address information that has been aggregated from Google.com.au. This holds true even for services that claim to be the best free AU reverse address lookup service. These free address lookup services are usually just trying to acquire and sell your personal data. Thankfully, a basic DIY reverse address lookup can be done simply and without a paid or free service. All one has to do is utilize Google.com.au and databases. After these two basic steps, an address search will yield the most accurate information available.
