I am having two account in AU. Receiving interest on that, however interest is less on current account. I don't know what to do to avoid it.

I am thinking to put are money in Current account so I can have less interest.

But on the other hand, I am having on free medical service in Pakistan and finding difficulties to arrange funds for that as well. I am thinking to put all money in my saving account and put all interest amount into my free medical service funds .
Will it be a good idea?
