You might look for seasickness bands, Wellard. They're wrist bands with a plastic insert (button, really) that hits a pressure point in the wrist and supposedly reduces the need to throw up.

They're also apparently useful for pregnant women, to offset morning sickness. According to my wife, however, she still felt nauseous, so she's not convinced they worked.

All I can say is that she went from puking regularly to puking every few days.... you make the call.

You should be able to find them in any marine store... at least, in the States. Don't know about Oz...
