Are our Aussie stars "too cool"? 5 Seconds of Summer accept their award on stage. Awkward acceptance speeches, no-shows by our two major artists and a refusal to do interviews were all too common on music's night of nights. Artist after artist whizzed past the media without stopping to chat, including Delta Goodrem, 5SOS, Jessica Mauboy, Chet Faker and Katy Perry, who refused to speak to media after her rant about local paparazzi this past weekend. Jessica Mauboy skipped most media interviews at the ARIAs. The normally very accommodating Mauboy, 25, was also surprisingly shy and declined most interviews, preferring to hang with her boyfriend Themeli Magriplis as they made their first major appearance as a couple in more than five years. Sia, undisputedly the lady of the night winning four awards, didn't send anyone in her place to accept her awards and the ceremony only screened one thank you video. Katy Perry accepted Best Female Artist gong on her behalf. Sia has today hit back at those criticising her non-appearance, saying she filmed four acceptance videos but only one was shown: Katy Perry declared Sia Best Female Artist at the ARIA Awards in Sydney. The notoriously shy pop star, whose big hit Chandelier dominated airwaves this year, took home Best Pop Release, Best Video, Best Female Artist and the biggest award of the night - Album of the Year for 1000 Forms of Fear. It was disappointing as we're sure Sia fans would've loved to have seen the singer acknowledge her big wins in person. Meanwhile, Iggy Azalea, who was writhing around on the American Music Awards stage with J. Lo on Monday night couldn't make it to her own country's awards ceremony. The rapper took home Best Breakthrough Artist but had her Fancy collaborator Charli XCX accept the award. "I'm going to drop it off to her and she's going to enjoy it," Charli XCX said. British popstar Charli XCX accepted Iggy Azalea's award for Best Breakthrough Artist. When electronica musician Chet Faker accepted his award on stage, the softly spoken dude gave the world's worst acceptance speech, collecting an award from Triple J's Matt and Alex (who were dressed as Chet himself and Sia).

What award is this? [looks at envelope] Oh, best male artist, OK. In the media room after his wins, Faker put his lackluster speeches down to tiredness from jet lag. Chet Faker accepts the award for Best Male Artist ... wait, what award was it?
