You are on 29S degrees and i'm at 22N so we are closer to eachother than either to europe or california up at 40N. So where I am is tropical i would think queensland might be similar. I'd suggest Reserva Privada OG Kush #18. Mine outdoor grows tall with lots of room for light to get in but with many well spaced big fat leaves. its ideal for letting breezes carry heat through. I haven't finished mine yet but when I do I assume it will be yielding well because of its basic genetic shape.Does anyone know any indica x sativa strain that would grow good in australia queensland were the temp reach 40.c in summer any help would be good '''
