Questions answered by this monthly evidence

How concentrated is the subclass 189 EOI score distribution for Marine Biologist?

EOI volume is spread across more score bands, with no majority contained in the largest three. NovenAI calculates that 70 points is the largest score band across Submitted, Lodged and Closed statuses, with 30 EOIs or 11.5 percent of the three-status total. The three largest bands are 95, 90, 80 points, containing 90 EOIs or 34.6 percent. This measures distribution concentration, not an invitation cutoff.

Is the Submitted EOI pool increasing or decreasing?

NovenAI compares Submitted status only. Submitted EOIs increased from 70 in August 2025 to 90 in September 2025, a change of 20 EOIs or approximately 28.6 percent across consecutive monthly snapshots.

Which states lead the subclass 190 and 491 Submitted EOI data?

For September 2025, NovenAI's state aggregation shows that QLD has the largest subclass 190 Submitted count at 80; NSW has the largest subclass 491 Submitted count at 70. These are EOI volumes, not state nomination allocations, invitation outcomes or an individual's likelihood of invitation.

How does NovenAI standardise and interpret SkillSelect EOI data?

NovenAI standardises the official data by occupation, visa subclass, status, score band, state and snapshot month. This report covers 7 available snapshots and 12 subclass 189 score bands with data. When the official source suppresses a cell below 20, NovenAI uses 10 as the analytical estimate, so the results are not exact application-by-application counts.
