Can I buy Meclazine Onboard?

I have taken Meclazine tablets in the past with no side effects. However when I went to buy them I was told Meclazine is no longer available in Australia. Can I buy Meclazine onboard the ship? Silly part is the cruise is Australia to New Zealand and I can buy Meclazine in New Zealand.
The only alternative I have is to buy Dramamine or similar but there is nothing "non-drowsy" available here. I would much prefer to take something I have taken before, without side effects, even if I have to pay extra on the ship.

If it is available, buy Bonine over the counter. It is the otc of Meclazine.
