Being a father of 2 little girls it's extremely frustrating when your kids have a fever late at night. If you're in SYdney, you need not fear, there's now a 24 hour chemist, we are little behind Perth and Adelaide where they have 24 hour chemists but nonetheless, we have one now.

I'm sure if you have a toddler with fever you won't mind driving an extra half hour to get some medication :)
No, I am not affiliated with this chemist, through my search I wasn't able to find any, by chance I saw an advert in the papers.
