I saw the aircraft last night (I live just to the north west of the opera house and was having a beer on my balcony). It looked noticably different from the other landings at around that time, the heading was more or less the same but it appeared a fair bit closer to me than the other planes. It's hard to estimate the distance, but maybe 1-2nm, certainally not less than that and probably not much more - else it would've flown overhead.
Of course it's not too easy to judge these things accurately from the ground, so take my views with a pinch of salt.
Apart from the position everything looked pretty much normal. The only thing that made me take notice is when I saw it a few minutes later off to the other side of me.
