Australian government debt could blow out by $620 billion by the end of the decade thanks to the coronavirus.

The Parliamentary Budget Office has crunched the medium-term impacts of the pandemic based on the Reserve Bank of Australia’s latest economic forecasts.

Its analysis released on Friday showed government debt in 2029/30 could be between 11 and 18 per cent of GDP ($500 billion to $620 billion) higher than it would have been otherwise.
