The Westin is a construction project consisting of two towers being undertaken by BGC in the city of Perth, Western Australia. Currently only one tower is under construction.
All of the glass is nearly up, and it certainly is a beautiful looking tower.
It is very rare to have a tower this tall topped out while still being completely bare of glass or cladding. But there it is.
These images depict the construction progress on the 26th of June 2016. Dual cores are visible progressing skyward.
