Diamond Princess onboard currency?

[Vader1111]

My parents are booked to travel on the Diamond Princess in January. They have been advised that only the Sun, Dawn and Sea Princesses are exempt from paying gratuities.

 

I'm guessing that this means the Diamond Princess hasn't been "Australianised". Does that mean that the onboard currency is likely to be US dollars?

yes the currency is in USD so they would have to pay the tips or reduce them

Thanks. Thought that might have been the case.
