from 45.085
(2) The markings:
(a) must be legible; and
(b) must have no ornamentation; and
(c) must be of a colour that clearly contrasts with their background.
--------------------------------
Any colour would appear acceptable, the 75mm that Mike quotes
(45.065) is the smallest size reference I found (only for gliders and
experimental aircraft though).
I read the CASR as allowing other markings (eg comp markings) on the
aircraft as long as they are not "confusing" to the rego marks. And
seems to be no restriction other than this.
Interestingly there is a AC 45-01(2) which notes an exemption (till
2012) for underwing marking of aircraft (less than 5700kg) which don't
fly outside of Australia (That's how I read it anyway).

This might be relevant. CASR Part 45 (volume 2 if you look for it via
the CASA website)
(c) in any other case as given in the following table.
Minimum heights of characters in markings on certain kinds of
aircraft

Item Column 2
Kind of aircraft Column 3

CASA has re written this in the last 3 years. I did phone them when I
was refinishing the BD-4 3 years ago. The CASA bloke admiitted the
then existing regs on this were in his words " a horse's arse". Only
that reg, I wondered?
This doesn't seem like much of an improvement and appears to differ
from the GFA manual. Quel surpise!
Is there still some reason for GFA to exist?
Anybody figure out how many sets of markings you need on a glider
according to CASA?
