The main limitation you'd have here would be the need to have a cheque account, but I've come up with a couple of suggestions you might want to look at.
The most straightforward would be AMP's eASYCash Management Account which has a cheque facility and pays 4.25% interest.
If you want a better interest rate and are prepared to accept slightly less convenience there are a range of places that will set up two accounts, one for transactions and one for savings, you'd just have to remember to transfer as much as you can from the transaction to the savings account by the end of each month to earn the most interest possible in the following month.
The highest ongoing business savings account rate we have on our site currently is the Bank of Cyprus Midas Account which pays 5.25%. You can compare all these accounts and their features using our business savings account comparison tool.
Best of luck with your search...
