National Cover Nearest Postcodes

Customer’s Postcode

Randomised per search. We avoid repeats for the same postcode in this browser.

How this works

Index = price indicator. 100 = cheapest nationally. 101 ≈ ~1% higher than the cheapest. Lower Index = lower price.
Results. We display 10 addresses ranked by postcode closeness (closest → furthest). Each postcode shows a random address from the dataset. Click “Find 10 nearest” again to see different samples (we avoid repeats within your session).

Nearest logic: absolute numeric difference between your postcode and those in the same state; one random address per closest postcode.

Tip: re-run searches to explore the price dispersion (Index & Premium) around your location.

About this database

Overview

The dataset contains unique address-level insurance records across multiple Australian states and hundreds of postcodes. Each record includes an Annual Premium and an Index—a normalised measure relative to the national cheapest price (100).

Understanding the Index

100 = cheapest address nationally (baseline).
101 ≈ ~1% higher than the cheapest.
Lower Index ⇒ lower relative price.
