An interesting comment was made in the “Macquarie Radio Network” thread:
The reason why Melbourne radio is far superior than Sydney radio, at least in the music radio front, is because of the fact that Melbourne has 1 more commercial music radio station than Sydney does (not counting the ‘fringe’ stations such as The Edge, C91.3, i98, Star etc), which is 3MP. Apparently, Caralis’ ownership of 2SM is letting them fall behind on that front. Their metro-wide community radio stations, such as RRR & PBS, is more superior than FBi & 2SER, whilst they also have a decent AM music station from a nearby regional market, which is 3GG from Warragul, which has a “Forever Classic” format, similar to that of 2GN/2XL. And their DAB-only stations, Aussie & Koool, are fairly unique in any metro market, in which it’s not available outside of Melbourne. To be fair, Sydney does have two dance-based DAB+ stations, Gorilla & Dance Super Digi, which is not offered anywhere else, either on FM or DAB+.
You could also say that if I was in Melbourne or Brisbane, I’d be listening to radio more than in Sydney, even if I don’t have a DAB+ radio. In other words, if I was in Sydney, having a DAB+ radio would be considered to be almost ‘compulsory’, due to the fact that most of the ‘fringe’ commercial FM stations that are receivable in most parts of Sydney are mostly Top 40-skewed (ie. C91.3, The Edge, Wave, i98 & Sea), with very few being adult music-based (Star & 2GO).
Back in 2012, when I was over in Perth, I generally found their local commercial music radio stations to be better than what Sydney offered back then, with or without DAB+ and/or the ‘fringe’ stations. At the time, 96fm was owned by Fairfax, which offered a rock-based format without the sport/talk that is present on Triple M in the eastern states. But now, since ARN took over 96fm last year, it became a Mix 94.5 clone, complete with their positioner of “Your Favourites from the 80s to Now”, as well as having a talk-based drive program. This means that Perth now has only 2 formats across its 4 commercial FM stations, with 2 having a CHR format (hit92.9 & Nova 93.7), whilst the other 2 have a AC format (Mix 94.5 & 96fm). This leaves 6iX, an AM station, as the only commercial music radio station to have a completely different format, in which it has a ‘classic hits’ format. With that in mind, having a DAB+ radio in Perth is now almost a requirement, as the only rock & easy listening stations in that city are found on DAB+ (ie. Classic Rock, MMM Modern Rock, Smooth & My Perth Digital).
With just one ownership change of a single Perth station (96fm), this meant that Sydney, Melbourne, Brisbane & even Adelaide now have better commercial music radio stations in general than Perth, even when not including the ‘fringe’ stations. In fact, Canberra is now not far behind Perth in terms of its commercial music radio stations, in which they also have 3 formats (1 x CHR = hit104.7; 1 x AC = Mix 106.3; 1 x Classic Hits = 2CA) across just 3 stations instead of 5! 
As a bonus, unlike all of the Perth commercial FM stations, at least Mix 106.3 has a music-based drive program if you prefer more music & less talk for the drive home.
