I am on the Sunshine Coast in Qld and have the same problem. My rosellas look fantastic, thick and lush, have had heaps of hot weather, heaps of rain and I prepaired the beds with horse manure, potash and a bit of blood and bone before planting. No fruit yet and it is now March. Maybe I put too much nutrient in. So looking forward to making jam!

If you try them again this year, cut back on the fertilizer. Rosella's don't need much if any fertilizer & can grow excessive foliage instead of flowering if there is too much. Well aerated soil that dries out occasionally seems to keep them happy, if you must, just a little seasol & charlie carp when small. Horse manure always needs to be well composted before using on your garden, unlike cow manure. Horse manure strips nitrogen from the soil whilst breaking down. Mix 2 cups of urea per wheel barrow of horse manure to speed up composting.

You are probably right - too rich a soil and plenty of water and heat. Manure potash and B&B don't have a real lot of N unless you put heaps on. Back off the watering if possible. If possible plant some leafy crop close by to take some N out of the soil.
