Citibank is offering their online savings account to new customers with a 6 months intro rate of 5.71% pa - 0.09% more than UBank (if you don't want to set up an automatic savings plan).
Of course, there is the usual things you'd expect from online saving accounts like no fees or minimum balance, etc

It would be interesting to see if Ubank will include Citibank in their rate assurance range.
ps. I have 2 Ubank accounts and am interested in moving to Citibank for 6 months then move back :)
Give it a few weeks when the RBA increase the rates and ubank will up their rates too.
