Not sure why you would suggest setting to sub-tropical when the Sydney climate is temperate.

Hi, my kohl rabi have failed to form the swollen tuber. They are 30cm tall and long stems, have been in the ground for 10 weeks, planted out from seedlings I raised myself and look really healthy. In raised garden bed, full sun, new soil and surrounded by successful snow peas, lettuce, broad beans and radish crops. What have I done wrong ?

gardeners saving seeds of kohl rabi or any brassicas end up with far too many seeds, much more than they hoped for. Add to that they save seeds from at least 3 plants going to seeds for cross pollination so exchanging them is imperative. Try at your nearest "local seed network" someone may have tonnes to give away or swap.
