Note that this is from an American's POV.
Accor Stadium (previously ANZ Stadium) is a large venue that has sport matches and major concerts. I decided to buy tickets the day of to see Lady Gaga during her Mayhem Ball, and the place was nearly full. Supposedly there was 80k people in attendance. It sounds chaotic being at a place with so many people, but it was actually quite smooth.
It's super easy to get there by train. You just get off at Olympic Park station and walk about 10 minutes to the stadium. Leaving might be a different story for people, but I left midway during Gaga's last song and didn't bother staying for the encore. Because of this, I was able to get on the train quite quickly without waiting too long. Of course other people had the same idea too, but it wasn't too bad. I've even watched people running from the stadium to the train station, which I thought was a bit much.
There's food stands outside before you enter the stadium. Think of them as food stands you'd see at the state fairs. You can get tornado potatoes on a stick, burgers, etc. There's also food inside the stadium, and the pricing is actually very reasonable vs. the ridiculous prices you see at American stadiums like LA's Crypto Arena. It's partial they don't rip you off like crazy and the AUD/USD exchange rate. I got a small gelato for $6, which would probably be more like in the $10+ range in America. You can get banh mi, sushi, burgers, pizza, gelato, etc. For drinks I think there was only beer, seltzer, and wine.
If you want to look for sit down restaurants outside the venue, it's quite limited. You'd have to go to the next town over for some good food, and it's about a 20 minute train ride.
This stadium is outdoor, so luckily the day I went wasn't raining. It rained the next day, and I would imagine it's unpleasant especially in the seats I had where there's no cover.
Overall, it was a good experience. Accor is a good venue for massive concerts.
Also for some background: I was trying to buy tickets to see Gaga in San Francisco on the day of the concert, and it was all resellers selling for $300+ for shit seats so I didn't go to that one. It was too ridiculous. In Sydney I bought directly from the official ticketing platform that morning of the concert for $120, not even from resellers, and it worked perfectly fine. My suggestion is if you can, sometime it's probably better to travel to see big acts elsewhere vs. back home if you have the means to. Like Taylor Swift, it was difficult to get tickets to go see her at So-Fi Stadium because of bots and scalpers, the reseller tickets were outrageously priced, and the experience is stressful. I imagine it was probably less stressful to get tickets in Sydney.
