They spawn in adult habitats during flood events in autumn and early winter, laying the  diameter eggs amongst flooded vegetation and leaf litter on the edge of the stream. As the flood recedes the eggs are left to develop out of the water; the high humidity provided by the vegetation keeps them moist.
