ABS director of Environment and Agriculture Statistics Lauren Binns said the 33% increase was largely because construction had begun in a number of major wind and solar energy projects.
"The increase in employment in 2016-17 was driven primarily by three states, Queensland, New South Wales, and South Australia " she said.
Queensland led the way, gaining an extra 1220 full-time equivalent jobs, due to the construction of large-scale solar farms.
“In recent years, Australia has experienced growth in the amount of energy derived from renewable sources.
"While the proportion of energy from renewable sources remains relatively small there is considerable interest in renewable energy activities and associated employment," said Binns.
While rooftop solar employment accounts for nearly half of the renewable energy jobs, the numbers have declined substantially over time, from a peak of 14,300 in 2011-12 to 6430 in 2016-17.
