From seed in Darwin this spring: Sweet Potato (for wet season), Kangkong, Corn, Pumpkin (tropical), Okra, Sweet Potato, Chilli, Asian greens (heat-tolerant), Lemongrass. That's a long list, which is the upside of Darwin's tropical conditions in spring, direct-sowing into raised beds gives you the best germination and the strongest root systems for the season ahead.

Darwin's gardening year is backwards to the south, your 'summer garden' is planted in April (start of dry season) not September. During the Wet season (October-April), elevated raised beds are crucial, Darwin soils can be waterlogged for days after monsoonal rain. If you want the printable, see the full Darwin planting calendar.
Darwin's spring suits raised beds for the simple reason that raised beds warm faster than ground-level soil, giving germination a head start and pushing transplants ahead by a week or two, which compounds across a 12-week growing window. The raised bed calculator sizes the bed; the companion planting guide fills it out.
