As POA for my mums finances I'm trying to find a financial institution that is offering decent interest rates. The best so far is ING with their Savings Accelerator earning 4.25% (variable) on balances of $50,000 and over. Does anyone know of any other institutions offering these kind of rates (MUST have Govt. guarantee). I need best possible rates as this is what's funding mums expenses, she also gets a part pension.
