Baby Hammock in Australia?

My sister just had a baby who has been suffering from colic. After doing research on baby colic I've decided to purchase a baby hammock, however I don't know what brand to buy. I checked out the Miyo hammocks but I don't like the fact that you can't see the baby through the sides and I would like better ventilation for my little nephew to guard against SIDS. As for the Hushamock hammocks, they have the same problem, and they're rather overpriced too ($495). The Amby Baby hammocks on the other hand, have been recalled due to their elevated design (apparently the elevation is deemed to be unsafe, whereas the flat hammocks are safe). Any other recommendations for purchase within Sydney Australia??
