Recent analysis from SEEK showed that ads for entry level jobs rose sharply over the pandemic before falling over the year to September:

As shown in the next chart, job ads grew fastest for the lowest paid jobs, which were running 50% above the pre-pandemic level:

Anglicare raised concerns this month that demand for starter jobs is far outstripping supply across country, posing problems for younger Australians seeking entry into the labour market:

Record numbers of international students combined with the softening economy spells bad news for Australians seeking entry-level jobs.
