AUB Group is closing its Sydney CBD premises in Philip Street and moving its head office to the northern side of the harbour where the Sura underwriting agencies business is based.

The company advised last week that its registered office and principal place of business would change to Level 14, 141 Walker Street in North Sydney from the start of this month.

The move consolidates operations at the one location, and will see about 200 staff working from Walker St.

AUB moved its head office to 88 Philip St in 2016 from its previous base on the Pacific Highway in North Sydney.
