The 2018 young rich list has been released, featuring 100 of Australia's wealthiest young entrepreneurs.

Australia’s top 100 wealthiest citizens aged 40 and under are worth a record $23.5 billion, with top earners, Atlassian co-founders Mike Cannon-Brookes and Scott Farquhar, contributing $7.1 billion, smashing the previous young rich list wealth record of $6.08 billion, which they held.

The list, compiled and published annually by the Australian Financial Review, has again been dominated by the technology industry, with the average age of rich listers sitting at 35.

Just ten women made the cut on the 2018 list, one up from the nine that made the 2017 list and eight in 2016, indicating a continuing trend and a noticeable gap in the number of mega-wealthy Australians.

Property players continue to feature in the rankings with Melbourne property developer Tim Gurner climbing into third spot on this year's young rich list.
