When entering figures off my clients daily takings sheet
How do I treat the CASH out from EFTPOS component?
I realise there is no GST on this but where do I put the initial entry so the account that is debited is not out of balance when the payment for Eftpos it made to the Bank Account

Cash out is actually cash deposited to your bank account in lieu of other receipts.

Your daily takings are made up of cash, cheques, and cards, so you enter the receipts crediting sales and debiting the bank account. When reconciling you have to be aware that the deposit will be split with one part appearing on the date of deposit and the other when the cards clear
