I am asking about the post code for Moorebank, On the forum, at the end of the PO Box it says 1875. The post code for the area is 2170. Which post code do I use?

Hi Bronco 1875 is correct.

A quote from Postcodes Australia below:
The postcode 1875 is reserved for non-standard use (PO Boxes, competition mail, government departments, large companies etc.) and as such the location data provided may not be accurate.
