The rapper, who is currently visiting the country for performances at events such as the Future Music Festival in Sydney, said that he is having a "wicked" time but still misses girlfriend Millie Mackintosh from Made in Chelsea.
Green told The Sun: "I don't think I've ever been this homesick in my life. Spending time apart is never easy but you just have to get on with it. It's pretty much a case of that aspect of my life being put on pause. It doesn't mean we stop thinking about each other.
"She understands my job but it doesn't take away the desire to be together and that's not possible right now. We talk all the time and we Skype. What can you do? That is distance and it's work, I have to do this and she's a busy girl.
"It's something we were both aware of when we started seeing each other and something we're both prepared to deal with. The good far outweighs the bad."
Green is performing at the Future Music Festival this weekend alongside Tinie Tempah, Jessie J, Fatboy Slim, Swedish House Mafia and New Order and he said that they have helped him get through the experience.
"I'm so happy they're here," he admitted. "Jessie is one of the nicest people I've met in this business. She is incredible and she's got good people around her. Everyone's each other's support as it's a weird job.
"I've never complained about being famous but people on the outside never really understand it like those who are involved. Being on tour can bring sleep deprivation, stress, worry and you lack security so it's good to have people there that can boost you when you need it."
