Passengers would prefer wider seats, than wider aisles, obviously Qantas prefers sardines.
Well here is a review:

The major criticism is the Economy seat. The seats are simply not wide enough for an average-sized adult to sit comfortably for 17 hours.
The seat is too narrow. Whilst I am tall, I am not particularly large. I was sitting next to someone who was also not ‘oversized’. We could not sit flat against the seat back side by side as our shoulders wanted to fill the same space. I spent the entire flight sitting at a slight angle so I wasn’t leaning into the aisle. Speaking of the aisle, I was bumped continuously during the flight, even though I was within the confines of my seat.
With 32 inches of seat pitch, the Qantas Dreamliner Economy seats do have more legroom than most Economy seats. But they’re also narrower than most Economy seats at just 17 inches wide. It’s true that most operators of the Dreamliner have opted for the same configuration with 9 seats per row instead of 8. (Japan Airlines is a notable exception.) But most airlines are not using these planes to fly non-stop from Australia to Europe.
