01

Scope of This Agreement

This Service Agreement governs the checking, savings, and money market deposit accounts you hold with Optus Bank. It works alongside — and doesn't replace — our Terms & Conditions, your account's rate sheet, and any disclosures provided when you opened your account.

Where a specific account disclosure conflicts with this agreement, the account disclosure governs for that account.

02

Account Types & Ownership

We offer individual, joint, and business deposit accounts. Ownership type determines who can access the account and what happens to it in certain circumstances.

OwnershipWho can transactOn the owner's death
IndividualThe named account holder onlyPasses per estate or named beneficiary
Joint, with survivorshipAny joint owner, independentlyPasses to the surviving owner(s)
BusinessAuthorized signers on fileGoverned by the business's operating documents
03

Deposits & Funds Availability

We credit deposits to your account as of the business day we receive them, subject to our funds availability schedule:

  • Cash, direct deposit, and wire transfers: generally available the same business day
  • Checks: the first $225 is typically available the next business day; the remainder by the second business day
  • New accounts or large deposits: may be held longer, as disclosed at the time of deposit

Cutoff time: deposits made after our posted daily cutoff, or on a non-business day, are treated as received the next business day.

04

Withdrawals & Transfers

You can withdraw or transfer available funds by check, debit card, ATM, wire, or through our online and mobile banking tools, subject to any daily or per-transaction limits shown in your account materials.

We may decline a transaction that would overdraw your account, exceed a posted limit, or that we reasonably believe to be fraudulent, and we'll notify you when that happens.

05

Overdrafts & Insufficient Funds

An overdraft occurs when a transaction posts for more than your available balance. You choose how we handle this for everyday debit card and ATM transactions:

Opt in to overdraft coverage

We may cover the transaction, and an overdraft fee applies as shown on your fee schedule.

Opt out (default)

The transaction is declined at no charge if funds aren't available.

Checks and recurring payments may be covered and charged a fee regardless of this choice, as permitted by law and described in your fee schedule.

06

Statements & Error Resolution

We provide account statements monthly, electronically or by mail based on your preference. Review each statement promptly.

If you spot an error

  • Contact us within 60 days of the statement showing the error
  • Provide your name, account number, and a description of the disputed transaction
  • We'll investigate and generally resolve the matter within 10 business days, or provide provisional credit while a longer investigation is completed
07

Closing Your Account

You may close your account at any time by contacting us, once any outstanding balance is settled and any pending transactions have cleared. We'll return any remaining balance by check or transfer to another account you designate.

We may close an account for inactivity, a negative balance left unresolved, or misuse, and will provide notice as required by law before doing so.

08

Amendments to This Agreement

We may amend this agreement from time to time to reflect changes in our services, technology, or legal requirements. We'll post the updated agreement here with a new "last updated" date and, where required, notify you directly before a material change takes effect.
