About 100 male players from 24 nations will compete for US$15 million ($21 million) in prize money and 750 ATP points, the ATP confirmed on Monday.

The two combined tennis events means Brisbane’s tennis fans will receive 10 days of top-flight tennis – from men's and women's players – at two events, instead of the seven days of the existing Brisbane International.

This year’s Brisbane International ran from December 30 to January 6, when Japan’s Kei Nishikori and Czech star Karolina Pliskova took out the men’s and women’s finals on Sunday night.

Several highly ranked women including Noami Osaka and Sloan Stephens began their 2019 tennis campaign in Brisbane and the likes of Roger Federer and Rafael Nadal have previously taken the court.

Premier Annastacia Palaszczuk and Tourism Innovation Minister Kate Jones confirmed the new format on Monday.

Tennis Queensland Mark Handley said it did not mean Brisbane would miss out on many of the world’s top-ranked male players.

“The Brisbane International this year had two of the top 12 players,” Mr Handley said.

“Under the new format [the ATP Cup] we are guaranteed four of the top 12,” he said.

“In order that is one of the top three, two of the top six and four of the top 12 male players in the world are guaranteed to be playing here in Brisbane.”

Mr Handley confirmed Brisbane and Sydney were the first two legs of the three-leg men’s international ATP Cup.

“At the moment there are negotiations going on with another city and there will be an announcement in due course,” he said.

Mr Handley said he wasn’t concerned the decision to stage the championship over three cities would dilute the appeal of Brisbane.

“No, I don’t think so, we have a proven track record here in Brisbane to deliver the world-class content and we will continue to deliver the world-class content for the people of Brisbane over more days,” he said.

The ATP Cup will see six pools of four teams each playing across the three cities, he said.

“They will be seeded according to the players’ ranking and the winners of the pool stages will progress into the final’s stages,” Mr Handley said.

Ms Palaszczuk and Sports Minister Kate Jones would not directly answer whether Brisbane would see a semi-final or a final of the new ATP Cup.

But Ms Palaszczuk said the best women’s tennis players in the world would be “exclusive” to Brisbane for one week in January as the lead-up to the Australian Open in Melbourne.

“Just think of the global audience that this is going to bring not only to Queensland, but to Australia as well,” she said.

Ms Jones said Queensland officials had opted to focus on women’s tennis in the lead up to the Australian Open.

“We want to own the first week of January for a women’s tennis spectacular. We will have the best women in the world competing here in Brisbane,” she said.

“We will have to have a look at the considerations in regards to the finals and semi-finals (of the ATP Cup).

“But we made the decision that we want to prioritise women’s tennis and be the home of women’s tennis for the first week in January.”

The ATP Cup would deliver bigger prize money and a more points for international male players, Ms Jones said.

“And that is why we feel very confident we will continue to have world class tennis for both men and women here in Brisbane.”

The main organising body for men's tennis is the Association of Tennis Professionals (ATP), while the counterpart for women's tennis is the Women's Tennis Association (WTA).
