Macqueen claims all "issues have been sorted" with Cipriani.
Season-ending injuries to Hugh Pyle and James Hilgendorf have helped to create an opening for Cipriani, who hasn't played since the Rebels' 28-9 loss to the Waratahs in late April.
He was dropped for breaking a team pact by going out on the town with Richard Kingi in Sydney and was suspended for the Rebels' two-week tour of South Africa shortly afterwards.
Speaking ahead of training at a cold and windswept Visy Park on Tuesday, Macqueen said that with only two rounds remaining in the Super Rugby season it's time for all parties to move on.
"The issues have been sorted between his management and the (players) association and the club," said Macqueen.
"It's good to have him available for selection.
"He'll be in the 22 at least."
Asked whether there was a future for Cipriani at the club beyond this season, Macqueen said: "It's totally up to Danny.
"If he wants it, it's there for him."
Fullback Mark Gerrard said Cipriani had worked hard to improve his standing with his Rebels team-mates during his time on the outer.
"He's got no choice, does he?" said Gerrard.
"That doesn't go (just) for Danny, that goes for all of us, we're in the same boat.
"We have policies in place and obviously Danny did break them.
"He missed the (South African) tour and that's a fairly significant punishment on the playing group's behalf.
"He's been training hard the last few weeks to get back in the squad and that's something I commend him on and his attitude.
"He's gone out to the schools and rugby teams to help out ... and that's something that we pride ourselves on.
"To have Danny back is great for the club and hopefully he can stick around for a few years to come."
Coming off last week's 40-3 loss to the Stormers which he described as the club's most disappointing performance, Macqueen said it was important for the Rebels to end the season on a high.
"Obviously we'd like to get some wins but it's really important to set ourselves up for next year and set ourselves up with a good foundation," he said.
"We've been reasonably happy with a lot of things that we've done this year but we've also got to be brutally honest when we've failed and we failed very badly last week.
"What we're playing for is pride, more than anything, and playing for Melbourne and what the side's become."
Macqueen said the Brumbies will present a huge challenge.
Not only will they be seeking revenge for their Round 2 loss to the Rebels at AAMI Park but they'll take enormous confidence from last week's upset win over the Reds.
"They probably played their best game for the season last week," Macqueen said.
