This is now old news but since it was introduced with little fanfare a year ago I'll post it here for Google's sake. You can finally use Citibank debit cards for POLi payments, which is useful if buying a Jetstar flight that's ineligible for direct deposit (< 14 days away) but you still want to avoid booking fees. For other supported banks, see https://www.polipayments.com/Banks
