Average penis size in Australia 🇦🇺
The published average stretched penile length for Australia is 15 cm (5.91 in), from Stewart et al., 2009 (225 men). That's 2.07 cm above the worldwide average of 12.93 cm. Stretched length is the flaccid penis extended to full length and measured from the pubic bone to the tip, which is the measure urology studies report.

The study behind it
The figure comes from Stewart et al., 2009, which measured 225 men. Method: bone-pressed, measured.
Note the method. This study pressed the ruler into the pubic bone, which captures the buried portion of the shaft and records roughly a centimetre more than a study resting the ruler on the skin, on the same man. A good part of the distance between this row and the lower-ranked ones comes from that decision rather than from the populations.
A sample of 225 men puts this in the mid-range of the studies used here.
How it compares
Australia ranks #4 of the 24 countries in the game. That is 2.23 cm above the median of this list (12.77 cm).
Both of those comparisons are against a list of two dozen countries chosen by which studies exist, not by any sampling of the world. Treat the rank as a fact about this dataset rather than a fact about the planet.

When Australia came up
Australia has been the daily puzzle 2 times so far. Each of those days has its own archive page.
What this figure is not
It doesn't describe any individual man from Australia. The spread between individual men inside a single country runs several times larger than the gap between any two countries on this list, so a national average carries almost no information about a person.
Nor is it medical advice, or a benchmark to measure yourself against. If size is something you've been worrying about, the guide on what the pooled data actually shows is a more useful page than this one, and a doctor is more useful than either.

How to read this figure
- Every study on this subject has to solve one problem: who agreed to be measuredRecruitment decides the answer before anyone picks up a ruler. It is the largest source of disagreement between studies and the least discussed.
- There are five ways to measure, and they give five different numbersMost arguments about this subject are two people quoting different protocols at each other. What each one measures, and how far apart they land.
- A percentile is not a grade, and almost everyone reads it as oneNomograms are the most useful thing urology has produced on this subject and the most reliably misread. What the curve is actually telling you is narrower than that.
- How a number with no source becomes a fact everyone knowsThe country maps on this subject are mostly fiction, and they got there by a repeatable process. Once you can see the process, you cannot unsee it.
