Billie Eilish has made history as the first female solo artist to top the Hottest 100, winning with her song Bad Guy.

It bettered tracks by former winner Flume, Mallrat, Tones and I and others, including Denzel Curry's cover of the 1996 song Bulls On Parade by Rage Against The Machine, which had been considered the frontrunner.

Eilish's victory is historic for two reasons: she is also, at 18, the youngest winner of the Hottest 100.

A top 10 full of female solo artists — there were five — might be symbolic of a slow, subtle change happening within the Australian music business, which has long lacked gender equality.

Meanwhile, Thelma Plum became the highest-ranking Indigenous artist in history when her song Better In Blak came in at number nine.

And Hilltop Hoods, at number 10 this year, racked up their 20th song in a Hottest 100.

Here are the top 10 songs.
