AustralianSuper Head Office and Physical Locations
AustralianSuper maintains its global corporate headquarters in Melbourne, Victoria, anchored in the Wesley Place commercial precinct at 130 Lonsdale Street. This location serves as the central operational hub for executive management, investment strategies, and corporate governance.
While global investment operations extend to strategic outposts in London and New York, national member services are anchored across Australia. In addition to the Melbourne HQ, AustralianSuper operates corporate regional hubs across Sydney, Brisbane, Adelaide, and Perth. Members visiting physical office spaces for complex inquiries or appointments should confirm operational hours in advance, as walk-in counter services are limited.
Mail Processing and Key Identifiers for Forms
Sending physical paperwork to the head office address can delay processing times. AustralianSuper uses a central postal scanning facility to handle member correspondence, statutory declarations, and paper claim forms.
All physical documents, certified identification copies, and completed forms should be mailed directly to the fund's official postal destination:
- Primary Postal Address: AustralianSuper, GPO Box 1901, Melbourne VIC 3001.
- Binding Death Benefit Nominations: Hard-copy forms requiring witnessing must be sent to the GPO Box to be legally logged.
- Employer Payment Identifiers: Employers configuring payroll software or clearinghouses must use the fund's Unique Superannuation Identifier (STA0100AU) and ABN (92 143 380 495) for compliance with Australian Taxation Office (ATO) SuperStream standards.

Digital Alternatives and Administrative Access
Throughout 2026, AustralianSuper has expanded its digital self-service tools, reducing the need for paper submissions. Most routine requests—such as updating contact details, switching investment options, consolidating accounts, or changing insurance coverage—can be executed instantly via the mobile app or online member portal.
Digital verification pathways now allow members to submit certified identity documents electronically for most routine transactions. However, physical mail to the Melbourne GPO Box remains required for legal subclass claims, paper roll-over authorizations, and formal dispute resolution filings.
