Do not fret, your honey is still good.
If your honey has crystallised, don't worry, this is totally normal for pure unadulterated honey.
Processed honey can look clear and lovely on your shelf for a long time, this has been heated up and altered for the consumer market.
Naturally Australian honey produced from native and exotic floral species is composed as follows:
Fructose 44%
Glucose 35%
Moisture 17%
Sucrose 3%
Other less than 1%
This means Australian honey is made out of over 80% sugar, which is a lot of sugar in very little water, and that make the solution unstable, but also means it will not spoil as the water content is not high enough to start the fermentation process.
Glucose being less soluble than fructose is the crystallisation 'starter' but other factors such as pollen or propolis in the honey as well as cooler temperatures can help speed up the process.
So in conclusion, honey that crystallises is good for you and you can still enjoy it. Some people actually like it as it's not so messy, but if you prefer it runny you can simply place the jar in some warm water to bring it back to its liquid state. You may need to repeat this a couple of time but please don't put it in the microwave as this will destroy all of the goodness in the honey.
