The output of sewerage and waste management in Australia has experienced significant growth from 2013 to 2023, increasing from 5.14 billion AUD to 22.88 billion AUD. Particularly notable is the sharp rise between 2014 and 2015, with a year-on-year variation of 151.26%, followed by steady increases. Over the past five years, the compound annual growth rate (CAGR) has been 6.62%. Year-on-year growth rates have been more moderate in recent years, with 6.63% in 2022 and 6.06% in 2023.
Future trends to watch include an anticipated CAGR of 3.67% over the next five years, leading to a forecasted output of 28.92 billion AUD by 2028. This slower growth rate suggests that while the sector will continue to expand, it may do so at a more stable pace compared to the previous decade.
