Yeah as Alan Kohler points out treasury and the treasurer got their guesses wrong by a wider margin than usual during the pandemic response.
Must have helped when framing this lot of guesses about the future outcomes.

In the depths of the 2020 panic, forecasts about what this one might do to the economy and government income and expenses were a complete guess.
But let it be recorded, and not forgotten, that Treasury, and therefore the Treasurer, guessed wrong, with the result that they over-compensated and under-forecast – by a lot.
Specifically, the $350 billion in government spending, and $350 billion in entirely coincidental Reserve Bank buying of government debt, was more than double what was required, so $250 billion of it was saved by grateful, bemused households.
Treasury said GDP would shrink by 1.5 per cent in 2020-21.In fact it grew by 1.5 per cent in that year, a 3 per cent turnaround.
In October 2020 the forecast for unemployment in 2020-21 was 7.5 per cent; it turned out to be 5.1 per cent.
So in the October 2020 budget, the estimate of the deficit for that financial year (2020-21) was $213.7 billion, but it turned out to be $134.2 billion.
The current financial year has a month to go, but the deficit is projected to be $79.8 billion versus the $112 billion that was forecast in 2020.
So across the two years of the pandemic, Treasury’s early estimates of budget deficits were out by a total of $111.7 billion, or 30 per cent.
So across the three budget statements over the past 12 months – that is, last year’s budget in May, the mid-year economic and fiscal outlook in December and last night’s 2022-23 budget – the “parameter variations” (that is, things resulting from better-than-expected economic outcomes) totalled $283.5 billion over the four-year forward estimates.
