Overlapping Identification Numbers?

I supplied a lot of personal details when starting my new job today, and it got me thinking. The Australian government keeps tabs on its citizens using a 9 digit tax file number. Meanwhile Australian phone numbers consist of a zero followed by 9 variable digits, if you include the area code. So now I'm wondering: is there anyone whose tax file number exactly matches their phone number? Or is there some unfortunate person who has most of the digits in common and keeps mixing the two numbers up?
