I'm not sure of the minimum income requirement.
No stated minimum income, but given the incredible similarity to the Westpac Altitude Platinum card, I'd wager a guess it'd be in the $30-$35k range that it is\was.
In saying that, the Altitude Platinum card from Westpac does give you the same points but for only a $50 Qantas fee (they're waiving the usual $150 annual fee for it), albeit with a $3000 spend in 90 days - see this deal.
Having had the Altitude Visa and this one through BankSA, I'd have to say that Westpac's app and online banking is leagues ahead of St George group's websites\apps, which are clunky to say the least.
