• With his cover of "Bulls on Parade" at #5, Denzel Curry became the artist with the highest ranking Like a Version to enter a Hottest 100, narrowly overtaking DMA's' #6-placed Like a Version in 2016. This is also tied as the highest ranking cover overall in Hottest 100 history. It joins Spiderbait's cover of "Black Betty" and Boy & Bear's cover of "Fall At Your Feet", which each ranked at #5 in 2004 and 2010, respectively.
• With "Better in Blak" at #9, Thelma Plum became the highest ranking Indigenous Australian artist in Hottest 100 history, overtaking A.B. Original's 16th-placed "January 26" from 2016.
• With "Exit Sign", Hilltop Hoods marked their 21st entry in an annual Hottest 100, placing them only one song behind the all-time record of 22 entries shared by Powderfinger and Foo Fighters.
• With "Unsainted", Slipknot broke the record for the longest absence between countdowns, having last appeared 19 years prior with "Wait and Bleed" in the 2000 countdown. Previously, Paul Kelly held the record with an absence between 2000 and 2016.
• The countdown featured 13 songs in a row by Australian artists, between positions 84 and 72, beating the record of nine consecutive Australian artists set in 2016.
• With "Rushing Back", Flume became the second artist to achieve both the #1 and #2 spots in separate countdowns, after Kendrick Lamar achieved this in 2017.
• Skeggs' cover of "Here Comes Your Man" marked the first time a Pixies song has ever featured in an annual Hottest 100. The band's songs have only ever previously featured in all-time lists in 1990, 1991 and 2009.

The annual triple j album poll was held across November and December and was announced on 15 December.[11]
