I loved the game, ordered the sequel and saw this -

So I thought this had to be done :-) 

It's different model from the one in Sydney Botanical Gardens, is not to scale but I thought an over the top Tallneck would be better there :-)  I also thought it adds a bit of balance to the skyline, with Crown Towers on the left, Sydney Tower in the middle :-)
