State-only charts ceased with the last survey dated 15/2/2010 as it was only a physical CD single chart hence it's demise but note the impact towards the end where state #1s were easy to achieve seemingly.
This list goes back to the start of ARIA and I will update KMR when someone sends it to me or when I get to it.
While they weren't published anywhere at the time to my knowledge, four pre-1990 ARIA state chart-only #1's I've obtained from ARIA are:
Underworld 'Underneath the Radar' - #1 in WA on 06/06/1988 (corresponds with printed top 50 chart dated 19/06/1988, as the charts were dated 13 days after the chart survey date in 1988, in keeping with AMR's dating). It seems that ARIA started the state charts one week before taking over the national chart, as this is one week before then.
Yazz and The Plastic Population 'The Only Way Is Up' - #1 in NSW on 17/10/1988 (corresponds with the printed top 50 chart dated 30/10/1988).
Jimmy Barnes 'When a Man Loves a Woman' - #1 in SA/NT on 14/11/1988 (corresponds with the printed top 50 chart dated 27/11/1988).
Transvision Vamp 'Baby I Don't Care' - #1 in WA on 21/08/1989 (corresponds with the printed chart dated 27/08/1989).
Unfortunately, the chart information I've obtained does not specify how many weeks were spent at their peak on the state charts, or whether this was the first or last week spent at #1.
Wow this information is amazing! I've always wanted the state #1s from the 1990s and 2000 (I already have a record from 2001 onwards). I'd love you to fill in the gaps at some point, obviously most would be the official #1 of that week but I'd imagine some weeks had former/future/current #1s on the same week in various states (i.e. I know in July 2000 in one week, Freestyler & Anastacia were #1 in various states
Very interesting info! I've always loved checking the state #1's as there used to be a few surprises compared to the national #1's. I remember how Eminem's When I'm Gone topped the chart nationally even though it wasn't #1 in any state.
A bit surprised to find out that some songs like I Can't Dance or Ode To My Family actually reached #1 in some states. Last edited:
