Just an up-date on this.
Having serached on the web site ( http://visa.via.infonow.net/locator/...SearchPage.jsp) which gary2jessica suggested (thanks guys) we located several EXPRESS TELLER ATMs in Cainta. They are under the Visa umbrella.
My wife's cousin is now using one of these to draw the cash I transfer from Nationwide, and we can confirm there are NO CHARGES at the ATM, so once again we can transfer cash without any charges either end, with an exchange rate very close to the 'inter bank' rate.
