Indeed! The person that acquired it didn't obviously know the rules.
Having said that, there has surely got to be more than one "Penny Wong" in Australia? I just did a quick search on White Pages, and in NSW there were 142 people registered with the surname Wong and the initial "P". 84 in Victoria. Maybe some of these were "Penny's"?
Then there would be all the "Wong's" that may have daughters called Penny. There are 2634 "Wong's" in White Pages in NSW. 1573 in Victoria.
And yes, I do have better things to do with my time .............
