Guinness World Records confirmed that David Richards had broken the record for the most lights on an artificial Christmas tree that had been held for five years by Universal Studios Japan in Osaka.
That 36-meter Japanese tree had set a new benchmark of 374,280 lights this month.
Richards, a Canberra lawyer and businessman, brought together a team of volunteers including an electrical engineer, structural engineer, welders, carpenters, masons and steel fixers to erect the dazzling display on a 22-meter steel tree.
"Some people say I've got quite a knack for getting people to do things for nothing," Richards said.

"I get people to do things for nothing because they know that I do things for nothing and I'm contributing my own money, resources, time and effort as well - so maybe they feel sorry for me," he added.
He set his first Guinness World Record in 2013 for the most lights on a residential property by covering his suburban home with 502,165 bulbs.
He set his second record a year ago by stringing up 1,194,380 LED lights in a public space. The 120 kilometers (75 miles) of multicolored wire woven in the shape of three interconnected giant, wrapped Christmas gifts in a Canberra mall was the largest ever image made of LED lights.
But records tumble fast in the competitive world of light displays. Richards' 2014 record was smashed in June at a hotel in Myoko, Japan, by an image of a dragon comprising 1,529,103 lights.
