Short answer: It depends on stage, but Australian VC deal sizes generally cluster as follows — seed deals around A$1.8–3M, Series A about A$8M, and Series B+ around A$20M, with the overall average/typical VC investment size in recent years reported in the A$10–20 million range. (cutthrough.com)

Notes and sources

• The Reserve Bank of Australia (speech, Apr 4, 2024) states that “the average deal size has clustered in the range of $10–20 million over recent years.” (This is an authoritative summary of industry-wide averages.) (rba.gov.au)
• Stage-level medians from industry reports show smaller seed rounds and higher later-stage rounds: Cut Through’s Q1 2024 summary reports median Seed ~A$1.8M, Series A ~A$8M, and Series B+ ~A$20M. (Use stage-level numbers when you want a more precise picture.) (cutthrough.com)
• APAC comparisons and historical context (Preqin et al.) indicate seed and later-stage deal sizes vary by region and have moved over time; averages can differ if reported as mean vs median or if large “mega” rounds are included. (financialstandard.com.au)
