Despite being the smallest particles, the neutrinos provide one of the greatest challenges for modern physics. The Standard Model of particle physics describes them as being exactly mass-less. Nonetheless, neutrino oscillation experiments provides precise measurements of their mass differences, but not the overall mass scale. Massive neutrinos have a signiﬁcant effect on the structure formation history of the Universe, which can be observed in the galaxy distribution today. I will present new results on the neutrino mass and number of species derived from large-scale structure in the three-dimensional galaxy map provided by the Australian WiggleZ Dark Energy Survey
