What's the catch with NAB Gold Banking?

I looked quite seriously at this account when i was choosing a new bank only a few months ago.. I was with ANZ for the unlimited account for $5 and had the V2 plus account, offering 6%p.a with 6 free transactions a month.

Now the reason i wanted a change, was to find an account i could get a good interest rate on, and pay all of my bills / direct debits for investments and everything, from ONE single account.

Anyone, long story short.. I signed up with Suncorp for there unlimited account, still costing me $5 a month BUT, i now get:

Unlimited transactions

FEE FREE ATM withdrawls for any ATM outside of QLD (good for me since im in NSW) but that doesnt include the private ATM's you'll see at pubs n what not, i just use the major banks ATM's to be on the safe side.

Savings account (only internet banking available though) but offers 7.15% and i have all my debits for investments come out, can bpay all of my bills and transfer anything to external accounts, all free of course.

So i have my salary directly deposited into this savings account.. put everything on credit and transfer a couple of hundred or so over into my normal account to withdraw of a week if i want to go out and do whatever. So simple, and seemed to be the best account for me.

Only problem is.. Im 2 hours from the nearest branch haha, but for now, works for me lol

I was looking around for an account back in April before a trip to Europe, and I chose this one (the NAB Gold Banking).

I withdrew money from overseas ATM's and wasn't charged any ATM Fees or currency conversion fees. When I withdrew $300 Euro, they did the exchange on the day so when I looked at my statement, it would show as a withdrawl of about $500 AUD. Whilst I didn't calculate the exchange rate exactly it looked pretty close to me with our dollar purchasing about $0.6 odd Euro. The amount withdrawn from my account in AUD changed slightly from time to time as I imagine the exchange rate varied from day to day.

I've kept the account and think it is great. I also have a NAB Isaver linked to it. Which is NAB's version of a high interest internet account. I don't think the interest is as high as some of the other internet providers but it is better than a standard account, and convenient as I can just transfer from the Isaver to everyday account on the internet and it is there instantly.
