"I was down on the doorstep of Venture Southland within a few days, in half an hour we were in touch with the stadium manager, and he said, Let's do it," recalled Mr Wilson, who won two World titles - individually and asa team - in the colours of native Scotland but who has now lived in New Zealand many years.
"Let's do it," he repeated. "That's been the whole attitude ever since."
Mr Wilson was unable to state the expected cost of running the championships, but the event has been made possible with major funding of $380,000 plus that of commercial sponsors.
The major funding comprised a major events grant of $260,000 from Governement's Ministry of Business, Innovation and Employment (MBIE), and $40,000 from each of the Invercagill City Council, the Invercargill Licensing Trust and the Community Trust of Southland.
While the hard-earned MBIE grant was pivotal, Mr Wilson said the event could hsave gone ahead without it. "It would have been at a smaller location," he said.
"This is good, the sheep are here, it's the middle of the season," he said.
It's taken a huge amount of volunteer participation, including the transporting of a six-stand shearing stand used for the Otago championships in Balclutha's War Memorial Hall on Saturday and it's re-erection starting in the ILT Stadium the next day.
First onto the board a tick after 11am today were six shearers, all from overseas, in the first heat of the All Nations Intermediate Championship, immediately highlighting the diversity of the 32 shearing nations taking part.
On Stand One on the stage built about the size of that of a major rock concert, was Elis Ifans, of Wales, joined along the board by Huques Lachaune, of France, Arsenio Sahiueque, Argentina, Masakuni Osawada, of Japan, George Orlof, of England, and Huw Rees, from Wales, only Sahiueque and Osawada being entries in the World Championships to follow.
They were new conditions to some, Sahiueque forgetting to clock-off with the button beside his stand and Osawada a determined battler taking the opportunity of a shearer keen to learn, his 57 sheep shorn on his first day in New Zealand last week being as many as he'd shorn in Japan all season.
About 600 specators saw the opening blows, most likely to be among the more than 3000 expected to watch the six finals on Saturday night.
The first of the World Championship events are tomorrow afternoon, being the heats in the first of three preliminary rounds of the glamour event, the machine shearing.
