Dates and opponents have yet to be announced, but WBA super flyweight champion Andrew and sibling Jason, who is ranked in the top five of the bantamweight division by all four major organisations, will showcase themselves on different cards at the MGM Grand in late June.

It's believed Top Rank Promotions plan to stage shows on Tuesdays and Thursdays next month, starting on June 9 and 11 American time.

Andrew is scheduled to make the first defence of his title.

Earlier in May, the brothers who live in Kingscliff, NSW - but originally hail from Victoria - were granted exemptions to enter the United States.

While they were the first fighters allowed back in the Top Rank gym since it was closed amid the coronavirus pandemic, American boxers will headline the first two shows.

The Moloneys get their turn later in the month possibly on June 24 and 26 Australian time.

Neither Moloney has fought at the MGM Grand, but they visited Las Vegas in 2017.

"Andrew and Jason took a photo of the MGM and I said to them 'boys, it might take a couple of years but believe me we are going to be fighting here,'" the siblings' manager Tony Tolj told AAP.

"They have always wanted to fight at the MGM Grand.

"Now with the bizarre way the pandemic has unfolded it's all coming to fruition."

The Moloneys sparred each other in their first sessions at the Top Rank Gym, but are now trading blows with fighters from New York and Las Vegas.
