SYDNEY, March 3 (Reuters) - Australia's economy expanded at a much faster-than-expected pace in the final quarter of last year and all signs are that 2021 has started on a firm footing too helped by massive monetary and fiscal stimulus.
The economy accelerated 3.1% in the three months to December, data from the Australian Bureau of Statistics (ABS) showed on Wednesday, higher than forecasts for a 2.5% rise and follows an upwardly revised 3.4% gain in the third quarter.
Despite the best ever back-to-back quarters of growth, annual output still shrank 1.1%, underscoring the havoc wreaked by the coronavirus pandemic and suggesting policy support will still be needed for the A$2 trillion ($1.57 trillion) economy.
The Australian dollar rose about 10 pips to a day's high of $0.7836 after the data while bond futures nudged lower with the three-year contract implying an yield of around 0.3% compared with the official cash rate of 0.1%.
"The ‘V-shaped’ nature of the recovery is everywhere to see – economic growth, the job market, retail spending and the housing market," said Craig James, Sydney-based chief economist at CommSec.
James expects the economy to rebound 4.2% in 2021.
Data on credit and debit card spending by major banks as well as official figures on retail sales, employment and building activity point to a strong start for this year.
Marcel Thieliant, economist at Capital Economics, expects GDP growth of 4.5% in 2021, "which implies that allowing for the slump in net migration due to the closure of the border, the economy will suffer no permanent drop in output as a result of the pandemic."
SUPPORT STILL NEEDED
Australia's economy has performed better than its rich-world peers thanks to very low community transmission of COVID-19 together with massive and timely fiscal and monetary stimulus.
Its economic output declined 2.5% in 2020, far smaller than a 10% drop in United Kingdom, falls of 9% in Italy, 5% in Canada and more than 3% in the United States.
"Our economic recovery plan is working, and today's national accounts is a testament to that fact," Treasurer Josh Frydenberg said in a news conference. "The job is not done," he added.
"There are challenges ahead. But you wouldn't want to be in any other country but Australia as we begin 2021."
