The Australian Bureau of Statistics estimated 790 new dwellings were completed in Tasmania in the June quarter in seasonally adjusted terms.

That was an increase of 96 compared with the previous quarter and the biggest quarterly total since 813 in the December quarter of 2015.

The value of Tasmanian housing starts during the quarter was also relatively strong.

It was estimated at $217.3 million in original terms.

While the total was significantly less than totals for the previous two quarters, it was substantially more than in most quarters in recent years.

The state was estimated to have 517 dwelling units approved but not yet started by June 30.

That was the highest total since the last quarter of 2018.

The ABS estimated the national number of dwelling starts fell by 5.6 per cent in the June quarter and was 8 per cent weaker than in the June quarter of 2019.

The state government, meanwhile, is spruiking what it describes as a $3.1 billion infrastructure construction blitz.

Infrastructure Minister Michael Ferguson said it would allow the government to complete a number of key infrastructure projects around the state, improving safety and "travel time reliability".

He said the government secured more than $400 million for roads and bridges in the federal budget.

Labor Leader Rebecca White said: "... infrastructure spending is all well and good, but the state and federal Liberals have demonstrated that they are incapable of building anything."

Home lending surged in Tasmania in August, despite the recession.
