So just thought I'd try my mobile number in http://www.reverseaustralia.com
It had my old address (5+ years ago) and then this little statistic:
"In 2006, there were 21,638 persons usually resident in 33 Barunga St Ngunnawal: 48.8% were males and 51.2% were females. Of the total population in 33 Barunga St Ngunnawal 0.9% were Indigenous persons, compared with 2.3% Indigenous persons in Australia."
God damn I knew it felt crowded.
