It's official: the most common path to ultra-wealth in Australia is property, with 50 of the BRW Rich 200 making their fortune from bricks and mortar. 
These 50 property rich listers, with their doyen Harry Triguboff at the top of the list after 31 years, are now worth a collective $68 billion.
That is almost three times the value of 16 resources rich listers who are now worth a collective $23 billion.
That divergence has happened rapidly and followed the simultaneous take-off of property values around the country and big drop in resource prices.
As recently as 2013, the gap between the collective worth of property and resource rich listers was a modest $7 billion.
That gap has widened to $45 billion as property rich listers grew their collective wealth by one-third between 2013 and 2016, while resource rich listers saw their collective wealth fall by almost half over the same period of time.
Two well-known rich listers illustrate the changing fortunes of property and resources.
In 2013, Gina Rinehart was worth $22 billion, while Mr Triguboff was worth $4.95 billion.
Just four years later, Ms Rinehart's wealth has fallen to $6 billion (with $900 million going to her daughter Bianca), while Mr Triguboff's value has doubled to be more than $10 billion.
Looking at all the 56 rich listers, it is clear that property is the industry that has created the most wealth in Australia, with resources peaking in 2011 before falling back to third place behind even retail.
The current net worth of long-time Rich Listers in the property industry (think Frank Lowy, Mr Triguboff and John Gandel) is now $41 billion.
This compares with $11 billion for long-time retail magnates, such as Solomon Lew, Gerry Harvey and Jack Cowin.
The combined wealth of long-time resource Rich Listers is more than $8 billion with Ms Rinehart owning three-quarters of the riches.
