Among the 50 “Series Unknown” rounds shown, the disclosed-size distribution is highly skewed: ACEN Australia’s $474M round (2025-04-14) is far above the rest, including IREN’s repeated $102M (2025-08-25) and $550M (2025-06-11) entries and other large rounds like Shift’s $128M (2025-04-16) and Eureka Group Holdings’ $118M (2025-05-01). The only other disclosed figures in the same high range as the biggest rounds cluster well below that top end.
The list also shows clustering by time and place. Rounds concentrate heavily in mid-2025, with many entries landing between 2025-06-01 and 2025-08-25 (including multiple same-date entries on 2025-08-25 and 2025-06-20). By geography, New South Wales and Western Australia appear repeatedly (e.g., Sydney-based IREN on 2025-08-25 and IREN on 2025-06-11; Perth-based Botanix Pharmaceuticals on 2025-06-10 and Venstra Medical on 2025-06-20), while “undisclosed” amounts recur (3 entries: Source Certain 2025-08-19, Heaps Normal 2025-08-11, and Cromwell Property Group 2025-05-22; plus Devicie 2025-04-17 is also undisclosed), indicating that a subset of rounds can’t be sized from disclosures. Sector-wise, Information Technology, Energy, and Financial Services each appear across multiple entries, spanning everything from Blockchain/crypto (IREN) to battery science (Sicona Battery Technologies $27M on 2025-05-20). Dates span 2025-04-03 to 2025-08-25, with the most recent round dated 2025-08-25 (IREN $102M and Send Payments $5M).

Frequently asked
How skewed are disclosed amounts within this “Series Unknown” Australia set, and what stands out at the top end?
The largest disclosed round is IREN at $550M on 2025-06-11, which dwarfs the next-largest disclosed figures such as ACEN Australia’s $474M (2025-04-14) and Shift’s $128M (2025-04-16). Outside that upper range, most disclosed rounds sit much closer to the lower-to-mid millions (for example, many entries at $2M–$11M).
Are there notable time clusters across the most recent months shown?
Yes. A dense run appears from 2025-06 through 2025-08, including multiple same-day rounds on 2025-08-25 (IREN $102M and Send Payments $5M) and repeated June dates such as 2025-06-20 (CathRx $710K and Venstra Medical $650K). The overall window runs from 2025-04-03 (Atomos $14M) to 2025-08-25, with the latest entries both dated 2025-08-25.
Which cities or states show up repeatedly, suggesting a geographic concentration?
New South Wales appears frequently via Sydney-based deals (IREN on 2025-08-25 for $102M and IREN again on 2025-06-11 for $550M; plus Security Matters $3M on 2025-08-05 and Superhero $11M on 2025-06-01). Western Australia also shows repeated presence through Perth-based rounds such as Botanix Pharmaceuticals $20M (2025-06-10) and Venstra Medical $650K (2025-06-20).
What proportion of rounds are not sized by disclosed amount (“undisclosed”), and where do those gaps fall?
Four rows carry “undisclosed” amounts: Source Certain (2025-08-19), Heaps Normal (2025-08-11), Cromwell Property Group (2025-05-22), and Devicie (2025-04-17). That means the disclosed-size analysis is based on the remaining 46 rows where an amount is provided.
Do particular sectors repeat enough to suggest a segment pattern within “Series Unknown”?
Several sectors recur. Energy appears across multiple entries (e.g., ACEN Australia $474M on 2025-04-14 and Amber Electric $30M on 2025-06-04), Financial Services also appears repeatedly (Butn $66M on 2025-07-02 and Shift $128M on 2025-04-16 among others), and Information Technology shows up in multiple rounds (Felix $10M on 2025-08-20 and Ceres Tag $2M on 2025-07-07, for example).
Are there any conspicuous outliers beyond the largest rounds, such as extremely small disclosed deals?
Yes. Atomos’ $14M (2025-04-03) sits mid-pack, while the smallest disclosed amounts in the visible set include Rumble Resources at $340K (2025-07-25) and multiple sub-$1M rounds such as CathRx $710K (2025-06-20) and Venstra Medical $650K (2025-06-20). These low figures contrast sharply with the top-end outliers like IREN’s $550M (2025-06-11) and ACEN Australia’s $474M (2025-04-14).
