please note its .com.au
and yes its very popular here , to the point if you reg a .com you may not be considered local to australia
they cost more than $2 a year !!! closer to 15 - 20
also we have .net.au .......for a serious project yes of course , just gotta live here
funny that
i believe .au.com is a sub domain
excuse me if i am wrong ?????
first i have heard of it
