Here's where it gets a bit fuzzy and I have to rely on a little bit of guesswork. Rose Gardens' podium in quite obviously rectangular but the cars now arrive at a podium car park that has a curve.
There's no way to pinpoint the actual place from this screen grab, the landmarks are too far away. I'm hoping someone out there will recognise some of the following features and help confirm the identity. For example we get to see a quick glimpse of the ironwork that covers the glass in the front foyer doors as well as the lattice work in the concrete around the podium at the back.
Then there is also a brief scene inside the foyer where the actor waits for the lifts.
And then there is a reasonable look around the apartment he enters, and its balcony area.
I'm sure there must be someone out there that remembers this rather stunning view. The angle on the Hilton and City Hall building (lower left of the bottom picture) certainly supports my supposition that this building is actually #11 Magazine Gap Road, but it's the next picture that has gone someway to convince me I am right (but hey! I don't always get these things right the first time). It's the view of the podium from the upper floor. The curve in the road and the distant but discernible presence of the three drains on the opposite side of the kerb (at the left end of where the black part of the pavement ends) match with the road outside #11.
Sadly even a brief glimpse of the front facade - with its central hexagonal window openings - reveals no further confirmation.
The building now standing at #11 is a fairly new one (opened in 1995) called 'The Harbourview'. Anyway, until someone can confirm I shall keep my eye open for shots of the 1960's mid-levels to see if #11 was captured at a time when it can be compared - or until someone who lived there happens on by (or perhaps was even there for the filming!)
