In all these examples the fourth numeral is indefinite; and the same statement is true of many other Australian languages.

But more commonly still we find 4, and perhaps 3 also, expressed by reduplication.
In the Port Mackay dialect[35] the latter numeral is compound, the count being _warpur_, 1, _boolera_, 2, _boolera warpur_, 3.

For 4 the term is not given.

In the dialect which prevailed between the Albert and Tweed rivers[36] the scale appears as _yaburu_, 1, _boolaroo_, 2, _boolaroo yaburu_, 3, and _gurul_ for 4 or anything beyond.

The Wiraduroi[37] have _numbai_, 1, _bula_, 2, _bula numbai_, 3, _bungu_, 4, or many, and _bungu galan_ or _bian galan_, 5, or very many.
