Autumn in Brisbane is the underrated second planting window, brassicas, leafy greens, garlic, broad beans all go in as the heat eases.

From seed in Brisbane this autumn: Tomato, Capsicum, Broccoli, Cauliflower, Kale, Spinach, Asian Greens, Carrot, Beetroot, Beans, Peas, Snow Peas, Radish. That's a long list, which is the upside of Brisbane's subtropical conditions in autumn, direct-sowing into raised beds gives you the best germination and the strongest root systems for the season ahead.
As seedlings in Brisbane this autumn: Tomato seedlings, Capsicum, Lettuce, Silverbeet, Cucumber, Zucchini, Tomato, Broccoli, Cauliflower, Leek, Bok Choy, Celery. Buying seedlings from a local nursery shortens the calendar by 4-8 weeks compared to seed, which matters most in Brisbane's shoulder windows.

The harvest peak runs across the season's middle month, when warm-season crops planted in the previous shoulder are coming into full production.
Brisbane's subtropical summers are tough on cool-season crops, don't fight the season. Focus July-September on your best planting window for tomatoes and capsicum. Fungal diseases like powdery mildew and early blight thrive in Brisbane's humid summers, choose disease-resistant tomato varieties and avoid overhead watering. If you want the printable, see the full Brisbane planting calendar.
Brisbane's autumn suits raised beds for the simple reason that raised beds drain faster and let you control the bed mix, both of which matter when the season's weather extremes try to either drown or bake your crops. The raised bed calculator sizes the bed; the companion planting guide fills it out.
