The company said in a statement that though year-on-year volumes were down, the growth from December to January was positive at 1.6%.
The community services and development sector showed the mmost growth for both December and January, up 16.8% and 15.7% respectively year-on-year.
The company said the average advertised salary was up, but only marginally, by 1.7%, with the average working out to $88,746 nationally.
SEEK managing director Kendra Banks said: "January marked the second consecutive month of positive month on month job ad growth at 1.6%, backing up the 0.2% rise in December.
"However, after Australia’s devastating bushfire season, and the uncertainty surrounding [the] novel coronavirus, we expect short-term growth to remain challenging as sectors such as hospitality and tourism, agriculture, forestry and fishing, retail and the higher education sector remain exposed."
Banks added that while the January 2020 data showed a drop for housing-related sectors like construction, trades & services, real estate and property, the company would keep a close watch "to see if this is the bottom of the downward trend, as we have seen signs of hiring activity stabilising in our data".
"This prediction coincides with the Australian Bureau of Statistics latest building approvals, which were up 2.7% year on year to December 2019," she said.
"There may be further support to underpin residential hiring activity as reconstruction efforts commence in Australia’s bushfire affected regions, and communities begin rebuilding over the course of the year."
