The best way to secure your machine is to restrict connections to only
accept from 127.0.0.0/8.  I did that and it restricted the number of attacks
I received by heaps.

Seriously though, how do you define "Australian IP addresses"?  Addresses
assigned to physical hosts currently located in Australia?  Machines
administered by Australian citizens?  Addresses assigned, in the first
(or final) instance, to Australian legal entities?

The problem is that addresses move around, and can be sub-delegated and
redelegated all around the place.  There are databases that try to keep a
track of some sense of "where" an IP address exists in meatspace, but
they're limited (at best).

My suggestion: don't bother trying to limit to some arbitrary ideal of
"where" an IP address is.  Block selectively based on actual activity.  Make
sure your machines are secure.  And don't stress about it.
