Mining magnate Gina Rinehart’s young version in Australia is a pair of technology entrepreneurs who founded the software company Atlassian. BRW 2016 Young Rich List, released on Thursday by the Australian Financial Review, says Mike Cannon-Brookes and Scott Farquhar are the richest young Australians with a combined wealth of $4.68 billion.

Their fortune doubled from $2.3 billion in just 12 months. It is the fifth year that the two techies have been topping the list which they first did in 2012 when they knocked off mining magnate Nathan Tinkler. Since then, Cannon-Brookes and Farquhar have held the number one spot, Daily Telegraph reports.

The doubling of their wealth came after they floated Atlassian on the NASDAQ exchange in the US in late 2015. The pair initially joined the list in 2007 when their combined wealth reached $26 million.

Another technology pair came in third and fourth places. They are Dave Greiner and Ben Richardson, founders of Campaign Monitor, a Sydney company. The two have a combined wealth of $543 million. In fifth place is Perth property developer Paul Blackburne, worth $483 million, whose Blackburne Property Group is dominant in the city’s apartment market and develops three to four large apartment projects annually, according to Australian Financial Review.

The remaining sixth to 10th place are held by technology investor Simon Clausen ($479 million), Melbourne property developer Tim Gurner ($414 million), Swisse Wellness CEO Radek Sali ($405 million), Compass founder Ori Allon ($316 million) and biotechnology company founder Sam Prince ($294 million).
