After listing in at least 5 general business directories, you should also look for any directories that specialize in your local area. Local directories can build a strong following in certain parts of Australia and your business could benefit from listing with them.
Here is a sample of local directories:
Easy Find Guide – Queesland
Perth Business Directory – Perth
Top 5 Guide– Perth
Stickybeek – Newcastle and Hunter Region
Toowoomba’s Online Directory – Toowoomba

There are many others. Try a Google search like “location directory” to find local directories in your area. For example, “Geelong directory”.
