Earn 2,000 bonus Qantas Points when you open your first Qantas Points Saver account with a $1,000 deposit in the 1st month^
^T&Cs Apply. New accounts opened 31/01/2023 to 28/03/2023. Min deposit $1k in first month. Excludes existing Qantas Points Saver customers. One points allocation per customer.
So you get 3.2% interest, with the bonus of 400 Qantas points per $1000/year (or 0.4 points/$ per year). Comparing to ING, you're losing 1.35% interest (or 1.35c per $1 to treat both as simple, which is not correct, but good enough).
Is 0.4 Qantas points worth 1.35c? Not at current market rates. But if you just want the bonus, I'm sure it's an easy couple thousand points.
