Land title documents updated this week show “Klaus Alex Birkenstock” bought the 525sqm whole-floor residence of the late Robert Blann, Kerry Packer’s bookmaker, on February 17.

The Barangaroo deal via The Agency’s Steve Chen is Birkenstock’s third property purchase since last December, including a Rose Bay waterfront mansion for $83.5m — the biggest deal of 2025 — where Alex and his wife, former model Vanessa, now reside.
