## How .com.au is priced

All 3 registrars whose .com.au pricing we have verified price it flat: the first year costs the same as every renewal, so there is no promotional rate waiting to expire. Verified renewals run $7.72 to $15.00 a year.

Because nobody discounts year one, the cheapest renewal is simply the cheapest .com.au: a $7.28 a year difference between the ends of the range.

Computed from the 3 verified .com.au prices this site holds, not from every registrar selling .com.au.
