Do you need to notify your credit card company when travelling abroad?

I am going to be travelling more often and I'm looking to get a new credit card, can anyone share experience of which card works out best. 

How does the balance transfer affect my credit?

Please advice which card is best for shopping

Where can I find the online application for the new credit card?

For the Orbital Elite Mastercard, do you konw how often the cash-back rewards are delivered?  is it yearly or quarterly?

Thanks

Does anyone know if there is a higher interest rate for cash advances vs purchases?

Thanks.

Hey, just looking over your site and the credit card offers are a little confusing.

Anyone have any recommendations on the best rewards card?  I'm okay with an annual fee if the benefits are worth it.
