I think its a type of fungal disease. Either cut off affected leaves or spray with some neem oil to control its spread. Good luck!

Try looking up White blister (Albugo candida). I get this is my broccoli at times and it may be what you are observing. There are pictures on the website www.agric.wa.gov.au/broccoli/diseases-vegetable-brassicas?page=0%2C1 Cheers Larry

Once flowers have formed, can the plant be productive or should I throw it out? This is broccoli I'm talking about.

Once broccoli has flowered it has gone too far.

You are in sub tropical by the climate zone here. If you live in a coldish part of Sydney you would be temperate. The best is probably to have the crop mature by July August.

Go to Vegetables and Herbs above and read about growing it in the TROPICS. Sounds like to live at the top end of Australia. Good luck.
