Gross domestic product (GDP) is expected fall by approximately 6% in the September quarter, due the economic impact Delta outbreak. But it will gradually recover over the December and March 2022 quarters growing 3.7% and 3.8% respectively, according to the treasury"s half-year economic and fiscal update (HYEFU). The GDP will reach 4.9% by 2023/24. Net debt will be higher at 37.6% of GDP in 2021/22 compared to 34.0% forecasted in May. The net debt peaks at 40.1% by 2022/23 before falling to 30.2% by the end of the forecast period.
