Another Australian here, torches aren't that expensive here for the most part... although lately I have seen some aquariums try to 'hype' up what they are now calling '24c gold torches' and sell them for more than they previously did. A large 20 head one was sold for about $750, and a bunch of 4-8 head ones were sold for between $175 and $250 (AUD) recently from a prominent facebook based seller here
My torches
green - 2 heads (fairly retracted in the photo but usually long extension) - $25AUD
gold with lime tips - 2 large heads - $150AUD
black with gold tips - 3 small heads - $35AUD
blue (hard to see its on the other side of the black one) - 1 medium head - $25AUD
