Mark Burrows sells Widgee Waa at East Kangaloon to tech billionaire Mike Cannon-Brookes

The mystery buyer of the Southern Highlands farm, Widgee Waa is reportedly Mike Cannon-Brookes, the tech billioniare.

The farm was recently sold by the retired merchant banker Mark Burrows.

Burrows is keeping the house, called Sugarloaf Farm, but sold some 380 acres of the 800 acres he holds at East Kangaloon.

There's talk of a $14.5 million sale price of the Widgee Waa offering.

The property is an aggregation built up over three decades, when he was head of investment bank advisory Baring Brothers Burrows.

The property has cattle farming infrastructure, equestrian facilities and a manager's cottage.

"I don't need two farms in the Southern Highlands and certainly not two of the largest land holdings," Burrows said ahead of the official marketing. 

Burrows had a long career in investment banking, commencing with Baring Brothers in London. 

The Nine Entertainment report did not have any confirmation on the buyer identify or sale price from Ken Jacobs and Christie's International or its conjunctional agent Meares & Co who always suggested it was likely to fetch between $30,000 and $40,000 an acre.

The last sale on Widgee Waa Lane was in 2012 when was paid $1.65 million for an 18 hectare farm (pictured). 

The 200-hectare property Comfort Hill at Sutton Forest sold in 2007 for a record of $15 million to the late international television show veteran Reg Grundy.

Last year, the Atlassian co-founder Mike Cannon-Brookes bought Kangaloon's 45-hectare Rosehill Farm for $5.35 million in March last year.
