The company, which describes itself as an employment marketplace, said in figures for July, released on Thursday, that month-on-month, Queensland (up 7.4%), NSW (up 6.3%) and Western Australia (up 5.2%) were the three states that had contributed to the increase in job ads for the month.
In Victoria, unsurprisingly, online job ads fell by 12.8% month-on-month as stricter lockdown rules took effect.
Among the sectors that contributed most to this decline were hospitality and tourism (-49%) and retail and consumer products (-18%).
"In July, small and medium enterprises did everything they could to innovate and find new ways to operate. However, we expect next month's job ad volumes to tell a different story after Melbourne entered stage four restrictions in the first week of August."
The SEEK figures showed that, apart from Victoria and the Northern Territory, the other states and territories saw a rise in online job ads, but at a much slower rate than in June.
"Queensland contributed positively to national job ad growth, with month-on-month job ad volumes up by 7.4%," said Banks. "Key industries contributing to this growth included hospitality and tourism, which was up by 31% month-on-month in July, and education and training, up 20% month-on-month in July.
"New South Wales job ad volumes grew by 6.3% month-on-month in July, with sectors including sales (up 17%), manufacturing, transport and logistics (up 16%) and healthcare & medical (up 16%) contributing to overall job ad growth for the state.
"Western Australia also performed well in July, with job ad volumes up 5.2% month-on-month. The construction, manufacturing, transport and logistics and sales sectors all made strong contributions to the state's growth, up 21%, 20% and 16% respectively in July."
