Sia and Billie Eilish from Los Angeles, Sam Smith from Abbey Road Studios in London, Sampa The Great from Botswana, Tame Impala from Perth, and Archie Roach from Warrnambool in regional Victoria will all beam into Sydney's The Star remotely on Wednesday night, making this year's ARIA Awards ceremony unlike any before it.

Australian Recording Industry Association chief executive Dan Rosen, who will attend his final ARIA awards as industry boss on Wednesday night after 10 years in the role, has been through plans A, B and C all the way past Z for this edition of the annual awards night.
