Potential Problems:

Hard frosts 
This is just part of life in Melbourne.  Some folks I know keep a greenhouse, and others have designed covers for their garden beds to minimise the impact. 
Un-seasonal heat
Always nice for we humans but this can cause premature growth in seedlings, cause some of the Asian greens and herbs to bolt to seed, and result in some of the bulbs to flower early.  

Cabbage Moth
Not an unattractive moth being small, white and delicate.  They often appear in  impressive numbers and will decimate your entire crop of broccoli and cabbage in under a week. Harvest your crops as soon as you can.
