Flo Rida and Sia finally edged their way into the top spot last night, but already they're under attack. Over on the albums chart, meanwhile, Adele just keeps on selling.
Flo Rida and Sia maintain the No.1 chart position for a second successive week with their single 'Wild Ones', but they may not be there for much longer - with a couple of singles rocketing up the charts with Flo and Sia firmly in their sights.
First and foremost is Laurent Wery's track 'Hey Hey Hey', which has shot up eight positions this week to No.2, causing Timomatic's single 'Set It Off' to drop to No.6 and Simple Plan's 'Summer Paradise' edging to No.4.
The biggest move (and perhaps the biggest threat), however, comes from Matt Corby, whose 'Into The Flame' EP has bulleted from No.42 to No.8. And with his single 'Brother' also vying for top spot on the iTunes chart on the back of Hottest 100 success, could he hit the top next week?
Hilltop Hoods and Sia score a new peak of No.11, with Drake & Rihanna's 'Take Care' right behind them after a six place rise.
The Black Keys' 'Lonely Boy' is up ten spots to No.15, but Taio Cruz' now three-times-platinum 'Hangover' is down three to No.16. 360 ftg. Gossling's 'Boys Like You' also sees some chart love - up ten places to No.19.
Pitbull and Chris Brown's 'International Love' goes platinum, Rihanna's 'We Found Love' hits the five times platinum mark. Kelly Clarkson's latest single 'Stronger (What Doesn't Kill You)' also goes platinum, along with Avicii's 'Levels'.
There's more Pitbull love down at No.37 with his Qwote collaboration 'Throw Your Hands Up' improving 16 places and entering the top 50 at No.37.
Not too far behind is James Morrison's track 'I Won't Let You Go', which was used extensively in promos for Channel 7 soapie 'Home & Away'. It's up 24 places to No.39, while the week's highest new entry goes to Knife Party, who are in at No.41 with their '100 No Modern Talking' EP.
Also scraping into the top half of the 100 this week is Jessie J's new tune 'Laserlight' with David Guetta - an eight place jump seeing it land at No.49.
Outside the top 50, Grouplove's 'Tongue Tied' is up to a new peak of No.51, Chiddy Bang's 'Ray Charles' improves to No.54, Rihanna and Jay-Z's 'Talk That Talk' bullets from No.91 to No.57 and 'Jumpstart' from These Kids Wear Crowns is up 23 spots to No.59.
After her sad passing last week, the classic Etta James track 'At Last' enters the top 100 at No.72, shadowed by a re-entry from Boy & Bear's 'Feeding Line'.
M83's 'Midnight City' debuts at No.78, Jessie J's 'Price Tag' re-enters at No.83 and there are other top 100 debuts from Florence & The Machine ('No Light, No Light' at No.95) and Nickelback ('Lullaby' at No.100).
Though Remote Control Records this week confirmed that Adele had notched up the eleven times platinum mark with her album '21', the charts still reflect the previous ten times platinum accreditation. Expect the sales figure to tick over in the weeks ahead - and yes, she's still glued into that No.1 position.
Foster The People's 'Torches' improves to No.2 (and goes platinum in the process) while the highest new entry of the week comes courtesy of Lamb Of God and their new album 'Resolution' which debuts in the No.3 position - their highest chart position in Australia to date.
The Black Keys' 'El Camino' rises to a new peak of No.5, Boy & Bear's 'Moonfire' is back in the top ten at No.9 and the Bangarang EP from Skrillex is now also a top ten starter.
Foo Fighters' 'Wasting Light' get the double platinum nod, Kasabian's 'Velociraptor' is up 18 places to No.27, but it's Celtic Thunder impressing with their 'Heritage' set. It rises an impressive 62 places this week to No.30.
New at No.32 is Enter Shikari's A Flash Flood Of Colour', Busby Marou's self-titled LP is up 37 places to No.40, Amber Lawrence's '3' debuts at No.41 and Chairlift's 'Something' is in at No.45.
Outside the top 50, Nero's 'Welcome Reality' is up 19 places to No.52, Kanye's Big Day Out appearance helps his album 'My Beautiful Dark Twisted Fantasy' move up from No.98 to No.61 and 'Her Best' by Etta James is in at No.65.
'The Very Best Of Slim Dusty' is up 33 spots to No.67, Arctic Monkeys' 'Suck It And See' is headed in the other direction - down 40 places to No.82 and there are further top 100 debuts from Harmony James' 'Handful Of Sky' (No.92) and Bond's 'Play' (No.94).
The Kooks' 'Junk Of The Heart' also falls 40 and down to No.100.
