Hi Alison - other than the swimming nappies sold via the pack in the supermarket, I'm not too sure about bathers for infants. Have you tried googling? DH and I went to a baby expo last year in Bris and there were several stands which exclusively sold baby bathers. Most had web addresses, but I didn't take any business cards, so I can't point you in the exact direction.

Otherwise maybe give the pool a call and see if they sell swimming nappies or bathers. I know the pool we take DS1 to sells individual swimming nappies over the counter. It might get you started, at least ...

Good luck with the baby bjorn!
