Hey mate, just another Kiwi here.
This season seems to be earlier this year. Most of my sativas have shown sex already! and they're pure satis too which is out of it.
I have 2 x Ace seeds Malawi clones, 3 x Cannabiogen Panama regular(2 confirmed females) and a Uzbeki indica hashplant from Cannabiogen also.
Malawi 6ft tall topped 3 times, exactly 2 months in the ground. I saw a couple of hairs here and there at the beginning of the month.
Panama 2 months veg, 5'5". topped 2 times and have suffered a seriously bad vine hopper infestation but are slower recovering with a pesticide and neem oil.
Uzbeki/Tashkenti. My only plant properly into flower.
What's your latitude mate? the higher up you go in aussie the earlier flowering because the days get shorter earlier than lower latitudes like Tasmania.
Canadian genetics can flower super quickly too, some of them finish in February!. What's your strain bro? indi or sati?, I personally think every aussie grower should be growing that crazy Mullumbimby Madness sativa, the original plants could yield up to 15 lbs and grow 20ft+.
