You can plant anything using the tropical guide on this site. You get good rain and should look into companion plantings to avoid pests, Good luck

We live on Norfolk Island and have just bought a house with a market garden and planted our first crop of broccoli 2 weeks ago. We have noticed the leaves have white squiggly lines on them and have small holes in them. We are planning on continuing the organic gardening of the previous owners.

Hi Katherine, the squiggly lines are from leaf miner and the holes in the leaves are from cabbage moth caterpillars. Check under the leaves for yellow eggs, and also pick off any caterpillars, i'd reccomend netting your broccoli.

In a 4 bed crop rotation is it safe to plant crops like brassicas in the same bed in both Autumn and Spring in the same year.

You can plant brassicas year after year after year if you like but then you are not doing crop rotation are you .Read up about crop rotation to what it achieves.

My broccoli has now gone to flower. Do I leave it in, or pull it out and plant more next year? Can't find a website to tell me if I keep it or start again. Thanks.

Pull it out. It's life cycle is ending.
