The rapper and producer will be headlining Brisbane festival Wildlands, Victoria's Beyond the Valley, and Perth's Origin Fields, and other yet-to-be announced gigs, in December in what will be his first tour since he publicly announced he was "banned from Australia", and congratulated Alison on her "win", in a tweet in July 2015.

The post unleashed Tyler's multi-million Twitter followers on Alison, sparking such a spate of rape and death threats that the global head of Twitter's internet safety personally phoned her to check on her mental health and wellbeing.
"I had to go to the police about it and there were people trying to track down where I lived, trying to threaten relatives and family members. I still haven't seen Tyler call out his fans to condemn that behaviour," says Alison.
The Department of Home Affairs' policy on public comment – "The department cannot comment on individual cases," a spokesperson told The Sydney Morning Herald – has spurred confusion over Tyler's visa status.
But despite his tweet, and unlike entry restrictions in New Zealand and the UK which were recently overturned, the rapper was never officially banned from Australia.
"We got confirmation from Immigration at the time that they never got to make a decision," says Alison. "We were in correspondence with Immigration so we know for a fact that he was never officially banned.
"It's unfortunate because his tweet led to a lot of abuse, and it didn't have to be that way."
The upcoming tour marks an interesting return for Tyler.
The 28-year-old, real name Tyler Gregory Okonma, has experienced a striking reinvention in recent years, emerging on his latest releases as a sensitive, soulful artist, thoughtfully and vulnerably examining themes of sexuality and alienation.
His jazz-inflected 2017 album Flower Boy earned a Grammy nod for Best Rap Album, while his most recent project Igor, featuring Solange and Kanye West, debuted at #1 on the US Billboard 200 chart and #3 on Australia's ARIA Chart.
He has also disavowed, or at least voiced ambivalence towards, his more polarising, provocative work, including early solo releases and work with Odd Future. Less than a handful of those tracks have featured on recent live setlists overseas.
"If it was 65-70 per cent cool, it was 30 per cent 'damnit Tyler, shut the f--- up!' I didn't realise I should stop yelling on songs until I was 24," he told Beats 1's Zane Lowe last month. "I finished editing Yonkers when I was 18. People don't realise we got famous off our rough drafts, our first dumbass ideas."
Alison says while she believes such "change is possible", a more explicit public statement from Tyler would be beneficial ahead of his first tour to our shores since the furore.
"A lot of people really look up to him and admire him, so he could use that to channel a positive message – in particular in Australia, where violence against women is still at epidemic rates," she says.
"I would love to see him speak out against those extremely violent and misogynistic songs that he created in his early days. And if he acknowledges the harm those songs can do, then I'd love to see him remove them from Spotify and Apple Music.
"Because if he's still profiting off that music and those lyrics, then he's still complicit in advocating the message those songs portray. And if he is still allowing those lyrics to influence young people, has true change really occurred?"
Organisers for the festivals have been approached for comment.
