Online entrepreneur Ruslan Kogan has increased his personal net worth by a massive $83 million in one year, skyrocketing up the BRW's Young Rich List for 2012.
Last year, the notorious headline-chaser came in 34th on the annual list, with a personal net worth of $62 million. This year Kogan soared up the list to eighth spot thanks to a new personal net worth of $145 million.
The BRW's 2012 list is dominated by members of the technology sector, with Atlassian founders and entreprenuers Scott Farquhar and Mike Cannon-Brookes bumping mining magnate Nathan Tinkler off the top spot this year.
The pair's combined wealth came in at $480 million, up from $360 million in 2011. The duo came in fourth in the 2011 list.
Tinkler suffered a $730 million drop in his own net worth, down from the record $1.13 billion that helped propel him to top spot last year.
Of the 100 named on the young rich list, 24 members came from the technology sector. The list tracks the wealth of Australia's richest under 41.
Also in the list is PC Tools founder Simon Clausen, with a net worth of $230 million (fourth richest), and Freelancer.com entreprenuer Matt Barrie, who makes the list for the first time with net worth of $50 million.
