A few ideas to put out there. Hopefully they will go with someone substantial.
Pop
- Kylie Minogue: She has a newish album and will have just finished a global tour in August so may be available. Australian names in pop don't get much bigger.
- Rose: She is big at the moment, and on the rise after that apt song. An Australian who just did the F1 theme and taps into the K-Pop / Blackpink scene. Could be worth a go to diversify interest in NRL?
Rock
- Foo Fighters: As someone else said they are playing the F1 in Singapore the day before. That is a short turnaround though and doesn't really leave time for sound checks etc
- Coldplay: Like Kylie, will just have finished a global tour in September and known for being good live, getting the stadium lit up etc. Pair it with glow wristbands and we are set.
- Oasis: Will be in between European and Asian legs of their world tour. Would need to return to Australia a month or so later for the Aussie leg.
- Metallica: Australian tour begins at start of November with no other dates in lead up. Could be workable?
Rap:
- Kendrick Lamar: He is signed up to some end of year concerts in Australia, including some smaller places like Canberra and Ballarat. A little controversial but could be gettable in that context?
