This is the highest interest rate that I can find atm. I'm currently with raboplus & their rate drop to 5% so I'm gonna move over soon after have a close look at their T&C.
Current rate @ Arab Bank Australia 7.20% ($1k+) / 7.25 ($10k+) / 7.35% ($100k+). Note: No longer valid, this is their current rate effective @ 17 December 2008
The Government's announcement to guarantee all Australian bank deposits also applies to Arab Bank Australia deposits. So, take advantage of our Online Savings account and earn 7.20% on as little as $1.
The 2nd highest rate is 6.50% @ Members Equity Bank
Edit
Thanks ozpete for the info please ignore the rate via Cannex above.
$0-$999,999 is 7.20% & $1,000,000+ is 6.20%
Nice Find but you may want to edit deal as it states on their site the rates are the same 7.2% for amounts up to $999,999 and 6.2% over (not 7.35% >100K as Cannex states)
