What is the difference between the current balance and current available balance?

Current available balance  takes into account online payments made during the day (following the last overnight settlement) and authorised overdraft for the given account. 

Current balance is the balance immediately after the overnight settlement – i.e. it does not take into account online payments made during the day.
