Just got a renewal offer from the dreaded Internet Name Group offering
to renew on of our .com.au names for 2 years ($220), 4 years ( $425), 6
years ($675), 8 years ($850) or 10 years ($1000)

Don't know who did the maths.  Maybe they can afford to be generous.  A
decent number of those ten year renewals and some people would be
tempted to retire to a warm country without an extradition treaty with
Australia.
