Australia's iron ore queen Gina Rinehart has maintained her spot in an elite list of the world's top 100 billionaires.
But she slipped down the ranks to number 75 in 2019, from 69 last year, although her current and depleted fortune of $US15.2 billion ($A21.5b) is nothing to sneeze at.
Ms Rinehart, who recently expanded into the cattle business, is still Australia's number one billionaire, according to the list compiled by Forbes and published on Wednesday.
She leads the local pack ahead of developer Harry Triguboff, packaging magnate Anthony Pratt and Atlassian software founders Mike Cannon-Brookes and Scott Farquhar.
Casino investor James Packer is ranked the world's 597th billionaire with $US3.6 billion ($A5.1b) and is number nine on the local list. But his fortune has declined to $US4.1 billion ($A5.8b) since 2018.
There are 2,153 billionaires in the world, led by Amercian businessmen such as Amazon's Jeff Bezos and Microsoft found Bill Gates.
This group has a combined worth of $US8.7 trillion which is enough to buy 124,000 high-end Gulfstream G-650 private jets.
Australia has 36 billionaires with a combined worth of $US114.4 billion ($A161.8b). That equates to almost four million average-price family cars.
