Self-service laundry on dawn

What type of Australian coin would I need for laundry on the Dawn?

Oh.......I think it's $1.00 coins - they have a machine in there that changes notes. I think I remember putting 2 x $1.00 in the washer and same in the dryer. (Only went in December - now I can't remember :eek:) But I do know that I changed a $10.00 note - and I did two washes over the 14 day cruise. The iron is free.

I saw people exchanging $2 coins for $1 ones at reception, so it would appear $1 coins are the go.;)
