Job advertisements statewide crashed by 30.3 per cent to 760 in April in seasonally adjusted terms as the coronavirus-driven economic crash bit deeply.

That is according to the federal departmental Internet Vacancy Index, which measures new vacancies lodged with major online recruiting sites.

Positions for doctors and nurses accounted for 130 of the Tasmanian vacancies, making them easily Tasmania's "most wanted" workers.

A further 50 vacancies were lodged in the health-related carers and aides category and another 40 for health diagnostic and therapy professionals.

General inquiry clerks, call centre workers and receptionists were sought by 60 of the vacancy lodgements.

There were 40 vacancies for legal, social and welfare professionals.

Job vacancies also crashed nationally in April.

The Internet Vacancy Index found there were 66,900 jobs listed for the month across Australia.

That was down by 48,900 per cent compared to March and 107,500 fewer than in April 2019.

ICT professionals were the most in-demand workers, with 5600 jobs listed.

Nurses (5100) were the other stand-outs, followed by general inquiry clerks, call centre workers and receptionists (3600).

The Reserve Bank recently flagged the possibility the downturn would not be as bad as feared.

"The Australian economy is going through a very difficult period and is experiencing the biggest economic contraction since the 1930s," Reserve Bank governor Philip Lowe said.

"Notwithstanding these developments, it is possible that the depth of the downturn will be less than earlier expected.

"The rate of new infections has declined significantly and some restrictions have been eased earlier than was previously thought likely.

"And there are signs that hours worked stabilised in early May, after the earlier very sharp decline."
