I'll send you a PM with my mobile.
Word of caution: Be very careful if you ever pick up the phone in a hotel! Depending on where you are staying, the charges are off the charts so try not using the in-room phone.
And don't send your laundry out using the hotel services, as it can be just as expensive. There are plenty of do it yourself laundry facilities that take coins to clean your clothes as long as you don't mind doing it yourself.
Try not to convert your money at the hotel or airport, as you will not get the best exchange rate. Try a bank. And this is the only good thing about using plastic, charge as much as you can abroad because you will get the fairest exchange rate using the credit cards.
One side note, I often visited the local casino's here in Vegas, more specifically the poker room, and I usually found a person from the country that I would be visiting and did a currency conversion with him, avoiding any service fees and bad x rate. Not sure if you live near a casino in Aus, but you might get lucky finding an American who's looking to dump some American Currency.
