Heard this on a radio commercial:
Get $75 when you open a new Complete Freedom account online or over the phone by 28 September 2018 and deposit $500 within 45 days. Conditions apply*
Deposit $2,000 by the last business day of the month for $0 monthly fees (otherwise it's $5 per month).
The fine detail:
Fees and charges apply. Read the terms and conditions available at bankofmelbourne.com.au before making a decision and consider whether the product is appropriate for you. Excludes customers who have held a Complete Freedom Account with BankSA, St.George Bank or Bank of Melbourne anytime from 3 September 2017. Not available with any other offer. To be eligible for this one off $75 cashback offer, customers must open a Complete Freedom Account online or over the phone between 3 September 2018 and 28 September 2018 (inclusive), deposit a minimum of $500 ($250 for customers under 21 or studying full time) within 45 days of opening the account; AND ensure the account remains open for at least 55 days from the date of account opening (“eligible customer”).

Edit: Some comments mention only being able to apply if in VIC, however terms don't state this. Your details may be on file if you've had previous accounts with BankSA, St George Bank even prior to 3/11/17 however.
