Japanese TFA opening

[G1Optimal]

The Sydney Opera House, then the battle underwater.

I could be wrong, but right near the very end was there a bit on an air battle (Megatron I think) with Centrepoint Tower in the background, or was it another cities skyline?

Might not match up to anything in the series, but that was a nice anime intro.

That is what i thought, i saw as well.... The "Centrepoint Tower" though it could just representation of Sudamac Tower

and for a moment i also thought that i saw the "Sydney Harbour Bridge" there to... but, after examining that bit more it looks like, it could be just a roof on a building . ( that sign on the front of it is really confusing me.)
