Honey will break your fast, unfortunately. It contains calories and will cause a spike in insulin.
For fasting-friendly beverages: You can do iced black tea, iced green tea, or iced herbal tea. No honey or sugar, just plain tea. A small squeeze of lemon is OK. For herbal teas, iced peppermint tea is nice. Or iced hibiscus tea (Celestial Seasonings “Red Zinger” is a common brand in the US; not sure if it’s available in Australia). Really, any kind of herbal tea you enjoy will be good over ice.
Cucumber water is delicious. Slice cucumber, put in jug of water, keep jug in fridge overnight.
Sparkling mineral water over ice is really nice when it’s really hot.
The herbal teas that are fruit-based, no sweetener, zero calories. Some have stevia, which some people don’t mind. I personally don’t really enjoy it.
Rosehip tea isn’t sweet but is wonderfully refreshing, if you can find it. Mostly these days is rosehip plus hibiscus, which isn’t the same.
