Albums

For the first time in ARIA chart history, Michael Jackson occupied the first three spots of the Albums Chart, after his death.
After winning season one of The Voice, Karise Eden simultaneously occupied the top three positions of the singles chart, the first time this has occurred in Australian chart history since The Beatles held the top six spots in 1964.#endnote_a|
On February 27, Ed Sheeran occupied the top three positions. However next week, "How Would You Feel" fell out of the top ten and was replaced by The Chainsmokers and Coldplay's "Something Just like This".
Note
a ^ Eden's songs made some of the biggest falls in Australian chart history in the following weeks. "Stay With Me Baby" fell to #54 the next week, the biggest drop for a #1 single in chart history, and left the top 100 the following week. It is currently the shortest time a #1 song has spent in both the Top 50 and the Top 100. "Hallelujah" dropped from #2 to #38 and then out of the Top 100 the next week. "I Was Your Girl" spent only one week in the Top 100, a drop of 97+ places, the equal biggest fall out of the Top 100 in Australian chart history.
