Yet another insane achievement by the UK singer.
It was only released in late November but Adele's multi-platinum third studio album 25 has remarkably achieved the honour of Australia's highest selling album in 2015.
After just six weeks on the chart and remaining unmoved from the peak position of #1 since its release, the record has also already been certified seven times platinum in the country, while her second offering 21 ranked as the 32nd highest selling album in the country.
Meanwhile the top end of the Albums chart is dominated by pop artists with fellow Brit singer Ed Sheeran's X coming in at #2, Taylor Swift's 1989 at #3, Justin Bieber's Purpose at #4 and Title by Meghan Trainor ranked at #5.
The highest Aussie selling artist of 2015 came in country singer Lee Kernaghan with his latest effort Spirit Of The Anzacs which placed at #8, a few spots ahead of Sia's 2014 acclaimed album, 1000 Forms Of Fear which finished at #14 and Vance Joy's Dream Your Life Away at #16.
