The schedule of sporting events has been released and for the next month people are being encouraged to consider which events they would like to attend.
At the end of the month, they can request tickets.
Organisers expect to sell 1.2 million tickets to the event.
Gold Coast Commonwealth Games Corporation chief executive Mark Peters said popular sports that have too many requests will go into a ballot.
"We know that some events like the hundred metres finals in track and field, and swimming will probably be over-subscribed," he told ABC Gold Coast.
"We want everyone to have a chance to get to the best events."
The move comes as the clock ticks over to just one year until the games begin.
Organisers of the Gold Coast games have marked the milestone with celebrations across the coast, the country, and the globe.
Mr Peters said he had mixed feelings about the fast-approaching deadline.
"It's daunting in one sense, but exciting in another," he said.
"We've been planning now for a long time, right back to the bid."
Ticket requests begin on April 24 and are available at the 2018 Gold Coast Commonwealth Games website.
