Crushed sugar cane pulp remains the most used source of renewable energy, with wind and solar hot on its tail.
The dry, pulpy residue known as bagasse is burned for fuel and was the largest source of renewable energy in 2018/19 at 23 per cent.
That's despite a nine per cent decline.
Bagasse is used by sugar mills to be largely self-sufficient, with the sugar by-product generating electricity and steam to power factories.
Wind made up 16 per cent of renewable energy consumption, followed by hydro at 14 per cent and solar panels with 13 per cent.
Renewable energy consumption lifted five per cent over the financial year due to strong growth in solar and wind.
The latest Australian Energy Update released on Friday shows renewables made up more than six per cent of total energy consumption, behind oil, coal and gas.
Oil topped the list at about 39 per cent, while coal amounted for 29 per cent.
Coal consumption fell two per cent in 2018/19, due to coal-fired electricity generation being displaced by renewables.
Natural gas accounted for 26 per cent of energy consumption.
Gas consumption was up two per cent, with increased use at LNG plants to support the expansion of exports.
Transport was the biggest user of energy followed by electricity supply, manufacturing and mining.
Energy Minister Angus Taylor used the data to praise the government's plan to expand the gas industry.
In terms of electricity generation, fossil fuels made up about 80 per cent, with renewables the remainder.
Natural gas-fired generation fell two per cent over the period, making up 20 per cent of Australia's electricity generation.
However, it rose again in the latter half of 2019 because of LNG production and export.
