Many years ago Max Gray in CSIRO told me that A. trichomanes almost always was associated with limestone. So I went out to the Cotter Cave, a local limestone outcrop, and sure enough, the area was 'infested" with the fern. Might be interesting for someone to check if it is still growing there (I no longer live in Canberra). The 2003 bushfires might have had some effect on it.

Asplenium trichomanes

I am estimating: " Rachis scales mostly 3–4 mm long; pinnae 22–56 mm long " <–quotation from Flora of NSW online PlantNet .
Including reasonably, I used your finger as an approximate centimetre wide 'stick' for scaling up to estimate some several pinnae have lengths longer than 25 mm (re.: _Pellaea nana_ ) .
