Mercury Nexus has a number of address fields. All are searching verified Australian addresses from a national third party database.
How to search for an address
Simply start typing in the field. Results from the search will appear automatically.
If your address includes Floors, Levels or Units it may be easier to actually leave that out and only search the main street number.
This is more likely to return a result which you can select. You can then add in the additional information.
