What is the AustralianSuper Fund’s address?

AustralianSuper maintains three distinct postal addresses, each tied to a specific type of fund correspondence. Using the wrong one won’t necessarily break anything, but your documents may take longer to arrive.

Postal super address

  • GPO Box 1901, Melbourne, VIC 3001 — Use this for all general super inquiries, contribution statements, and member correspondence (AustralianSuper Official)

Physical office address

  • Level 33, 50 Lonsdale Street, Melbourne, VIC 3000 — The Melbourne head office, located in the CBD near the Flag Gardens and Collins Street intersection

Retirement services address

  • Locked Bag 6, Carlton South, VIC 3053 — Specifically for members in the retirement phase, including those receiving account-based pensions (AustralianSuper Official)

The implication: if you’re mailing anything related to a pension or transition-to-retirement income stream, route it to the Carlton South address. General contributions and balance inquiries go to the Melbourne GPO.

How do I contact AustralianSuper?

The phone remains the fastest route for most member queries, though the fund’s online portal handles a growing share of routine tasks.

Phone numbers

Email and online contact

  • The fund’s logged-in portal at AustralianSuper official website handles contribution updates, address changes, and benefit statements without requiring a phone call

National Relay Service

  • Members with hearing or speech impairment can access support through the NRS at AustralianSuper official website

What this means: for routine updates, the online portal saves you the wait. But when something is time-sensitive — a disputed contribution, a rollover delay — calling cuts through faster than a web form.

Where is the AustralianSuper located in Melbourne?

The head office sits on the 33rd floor of a prominent city building, placing it among the major institutional locations in Melbourne’s financial district.

Head office location

  • Level 33, 50 Lonsdale Street, Melbourne, VIC 3000 — Accessible via Flinders Street and Southern Cross stations; tram routes along Lonsdale and Collins streets serve the area

Directions and access

  • The building is adjacent to Collins Square and close to the Flag Gardens plaza. Members considering a visit should check whether appointments are required for specific services by calling Member Direct first

The catch: walking in without an appointment may not guarantee immediate service. Confirming availability by phone ahead of a visit prevents wasted trips to the CBD.

What super details do I send to my employer?

When you join AustralianSuper, you hand your employer a short list of identifiers. Getting these right from the start prevents contribution delays and SuperStream matching failures.

Fund details required

  • ABN: 65 714 394 898 (AustralianSuper Official)
  • SFN (Superannuation Fund Number): 268 351 945 (AustralianSuper Official)
  • USI for Super: STA0100AU (AustralianSuper Official)
  • USI for Retirement: STA0002AU (AustralianSuper Official)

Letter of compliance

  • AustralianSuper can provide a letter of compliance confirming fund registration and compliance status — request this through Member Direct if your employer or accountant requires it for SMSF establishment or audit purposes

Electronic service address

  • For employer contributions to industry funds like AustralianSuper, employers typically need the USI rather than an ESA. ESAs are specifically required for SMSFs under SuperStream rules (Australian Taxation Office)

Why this matters: providing the wrong identifier code to your employer — for example, confusing the USI with an ESA — can cause your contributions to bounce back or land in a suspense account. AustralianSuper’s USI codes are listed on the fund’s education page.

What is the AustralianSuper electronic service address?

ESA requirements apply specifically to Self Managed Super Funds, not to industry funds like AustralianSuper. Understanding this distinction saves confusion when setting up employer contributions or processing rollovers.

ESA for super payments

  • An ESA is a secure, government-regulated digital address that lets SMSFs send and receive SuperStream messages. Under Australian law, all SMSFs must have an ESA to process rollovers and receive employer contributions (Australian Taxation Office)
  • The SuperStream system matches payments using three details: the fund’s ABN, bank account details, and ESA. This digital layer lets the ATO capture contribution data in real time (SMSF Australia)
  • An ESA is technically a type of web address but is provided as an alphanumeric code. It is case-sensitive — using incorrect upper or lower case characters on any form will cause matching failures (Canstar)

Account name and setup

  • The same ESA can be shared across multiple SMSFs — it is not unique to a single fund. ESAs are typically set up when an SMSF is established, and members must ensure their ESA remains active, as some providers allow them to expire (Canstar)
  • SMSFs can obtain an ESA through an SMSF messaging provider, tax agent, accountant, or some banks. If you do not use an SMSF intermediary, you must register directly with a messaging provider (Australian Taxation Office)
  • When rolling funds out of an industry fund to an SMSF, the receiving SMSF must provide its ESA so the sending fund can complete the SuperStream transfer (Heffron)

The trade-off: AustralianSuper’s industry fund structure means members don’t need to manage an ESA for everyday contributions. But if you eventually transfer to an SMSF, the ESA setup and maintenance fall entirely on you — and lapses can block incoming contributions.

Bottom line: AustralianSuper maintains three distinct postal addresses for different member situations — general inquiries, retirement-phase correspondence, and the physical Melbourne office. Employer super contributions rely on the ABN and USI codes listed on the fund’s own site, not an ESA. SMSF members, however, must actively manage their ESA to stay compliant with SuperStream requirements.

Upsides

  • Multiple address options cover every member scenario from general contributions to retirement income streams
  • Member Direct line (1300 300 273) staffed until 8pm on weekdays
  • USI and ABN publicly listed on the fund’s education page — no need to call for basic identifiers
  • Online portal handles routine updates without requiring phone contact

Downsides

  • No dedicated ESA provided for employer rollover setup — members leaving for an SMSF must arrange their own ESA
  • Physical office accessibility and walk-in policy unclear without calling ahead
  • Locking Bag address only relevant to members already in the retirement phase — less useful for younger members

What members and employers say

Members calling with contribution issues are often dealing with an employer who used the wrong USI or left out the ESA field entirely. Getting those three details right saves everyone time.

The SuperStream system is only as good as the data that goes in. An expired ESA or an incorrect USI code means the ATO can’t match the contribution, and the money sits in a suspense file until it’s resolved.

Frequently asked questions

What happens to my Super if I move overseas?

AustralianSuper accounts remain active regardless of your location. Keep your contact details updated through the member portal and ensure your employer has the correct contribution details. Your super will continue earning according to the fund’s investment options.

How do I join AustralianSuper?

Visit australiansuper.com, call 1300 300 273, or ask your employer to submit your fund details. Employers using defined contribution schemes may nominate the fund directly for new employees.

What is AustralianSuper letter of compliance?

A letter of compliance confirms your fund is registered with the ATO and meets regulatory requirements. Request it through Member Direct if your employer, accountant, or auditor needs verification of your fund’s status.

What is AustralianSuper account name?

The official account name is “AustralianSuper Superannuation Fund.” Your employer may ask for this when setting up contributions. Your member number — visible on statements and in the online portal — is the identifier tied to your specific account.

What superannuation details do I need for Australian Retirement Trust?

Australian Retirement Trust (ART) is a separate retail fund — not affiliated with AustralianSuper. If you are comparing or transferring, confirm which fund you hold and use that fund’s specific ABN and USI codes. The two funds are distinct legal entities with different addresses and identifiers.

What is AustralianSuper app?

The AustralianSuper mobile app lets members check balances, view transaction history, update personal details, and track investment options from their phone. Download it from the App Store or Google Play and log in with your member credentials.

How do I use AustralianSuper ESA?

AustralianSuper, as an industry fund, does not provide an ESA for employer contributions — it uses a USI instead. ESA requirements apply to SMSFs only. If you are transitioning to an SMSF, contact an SMSF messaging provider or your tax agent to set up your ESA before directing employer contributions to the new fund.

The upshot

For members sending or receiving super, the critical identifiers live on AustralianSuper’s own education page: ABN 65 714 394 898, USI STA0100AU for super and STA0002AU for retirement. Employers who paste these correctly the first time avoid suspense-file delays.

Why this matters

AustralianSuper and Australian Retirement Trust are entirely separate funds. Members who confuse the two — using one fund’s ABN for the other’s contributions — will find their payments unallocated. The addresses and identifiers are not interchangeable.

For members and employers alike, the path forward is straightforward: pull the identifiers from AustralianSuper’s official education page, confirm the correct postal address for your correspondence type, and update your records when moving between contribution and retirement phases. The ATO’s SuperStream matching depends on getting those three details right every time.
