The Federal Treasurer remains convinced that an increase in Omicron cases across the country will not derail Australia’s economic rebound, following last year’s COVID-19 lockdowns.

It comes as new figures released by the tax office show 485,000 jobs have been created across the country since September.

Josh Frydenberg said the county has experienced a job boom in recent months.

“Small businesses across the country that made it so hard in the beginning (in the pandemic)… are now coming back better,” Mr Frydenberg told Sky News on Monday.

“We are starting to see these jobs coming back and it looks very promising for the Australian economy.”

Data from the Australian Taxation Office on Monday comes after the unemployment rate recently fell to 4.6%, which was a 13-year low.

Job vacancies are also at their highest level in 13 years, with more than 250,000 jobs available.

ATO data covers the period following the release of the blockages caused by the Delta variant in NSW, Victoria and ACT.

COVID-19 restrictions across the country have eased after the lockdowns ended, but the number of infection cases has increased in recent weeks due to the spread of the Omicron variant.

But despite the rise in infections, Mr Frydenberg said the economic recovery was still on track.

Responding to calls from leading economists for a more aggressive approach to migration to help fill vacancies after the pandemic, the treasurer said it would be done in a measured way.

“We will continue to have a balanced and thoughtful approach to migration,” said Frydenberg.

“We have seen throughout the pandemic last year and the year before, population growth (was at)… the lowest level in over a century.

“This is going to be one of the most permanent impacts of COVID on migration. “

Skilled workers, visa holders and international students can return to Australia without needing a travel exemption since mid-December.
