McIlroy, who has won events all over the world, says he would like to see the Australian Open and South African Open being given elevated statuses due to the quality of courses and level of interest in those countries.
The 34-year-old would also like to see top players playing more regularly in places like Singapore, Hong Kong and Japan in a global tour that, to him, would resemble the current Formula 1 schedule.
“Whether they are rotated on the new global circuit, or we go with the same ones every year, I’m OK with either,” he said.
“The Australian Open, for example, should almost be the fifth major. The market down there is huge with potential. They love golf. They love sport. They have been starved of top-level golf. And the courses are so good.
“The South African Open is another I’d have in the mix. Then you have places like Singapore and Hong Kong and Japan. What a market Japan represents. That would be another opportunity.
“We could end up with something that resembles Formula One, but with a little more of an American presence.
Throw in the four majors and you have a brilliant schedule for the top 70-100 guys, whatever the number is.
“We’d have, say, a 22-event schedule. That would look pretty good to me.”
