How to Grow Brussels Sprouts in Cool Temperate Australia

Soil
Moist, fertile soil with plenty of compost (Seeds of Plenty). Firm soil helps the tall stems stand.
Salt
Moderately sensitive. Copes with a little salt, but the harvest drops on salty bore water.
Sunlight
Full sun, with shelter from wind because tall plants topple (Yates).
Spacing
60cm apart
Watering
Keep the water even. Dry spells stress brassicas. No exact water figure was found.
Good companions
Nasturtium, Dwarf Beans, Onion, Cucumber, Dill
Keep away from
Tomato, Climbing beans, Capsicum and chilli, Eggplant
Grow before it
Legumes (Beans - Dwarf, Peas, Broad Beans)
Grow after it
Fruiting crops (Tomato, Capsicum, Zucchini)

Give the bed 3 turns before brassicas go back in. The cabbage family is hungry for nitrogen and shares club root and other soil diseases.
