Oh great topic although I suspect ultimately a bit depressing 
My first memories of radio were really “funtastic” 4MB Maryborough in the mid to late 70s. On holidays at my grandmother’s house at the beach it was always 4BU again in the late 70s and early 80s. 4BU seemed obsessed with certain bands. Every time I hear Little River Band I think of them.
1980 - 1985 was spent trying to get good daytime reception of 4GY who had a top 40/AC format and loved the “new romantics”. Whenever I hear certain Spandau Ballet songs like Round and Round I think of 4GY. They also sounded so much more professional and polished than 4MB or 4BU. Nighttime was spent DXing stations in particular 4MK and 4HI used to come through best. But I’d just go slowly up and down the dial. As a station faded out I’d move on. Lots of fantastic early 80s music! It was a great time. I recall in particular when Careless Whisper/George Michael seemed to be constantly played on nearly every station!
1985 - 1990 when I came to Brisbane for Uni and work it was all about FM 104 and Stereo 10. This would be my golden era of radio. I didn’t know how lucky I had it and I had no idea it would end! I still think for me there will never be another station like FM104. It was just perfect for me.
Things went downhill a bit in the 90s both musically and station wise. MMM wrecked FM104 and I’m still not over it. B105 was ok at first but eventually I switched off. QFM/Star at least provided a good listen.
Spent a few years working in Sydney so it was mainly WS, Mix and MMM. Interestingly on my regular drives up to Brisbane I rarely found anything worth listening to except the Newcastle stations.
The 2000s were even worse at first. 97.3 was a big disappointment to me when it went to air. Was so looking forward to the 3rd official FM in Brisbane but it was such a letdown. So bland and repetitive and safe. Still can’t stand it to this day.
So mainly listened to a bit of Triple M, 4KQ and 4BH.
Then I discovered Breeze and Rebel which got me enthusiastic about radio again. And River 949 also became a staple in the car.
Then I started streaming some overseas stations.
Today I listen to 100% DAB at home and in the car. Smooth, Easy Hits, Triple M Classic Rock and Greatest Hits mainly. At work I stream Absolute 80s and BBC2 from the UK.
The only FM I listen to occasionally is Breeze, Rebel and River.
I still love radio to this day, although I listen to zero mainstream FM.
Sadly nothing will ever come close though to the 80s golden era for me - 4GY, Stereo 10 and the perfection that was FM104
