Tentatively this may be Limnaecia sp. ANIC 14 which appears to have a northern Queensland ditriburion including Townsville. See https://bold-au.hobern.net/specimen.php?processid=ANICW1453-11
@ibaird Certainly close, the problem I had with most of the Limnaecia was the apical joints of the palps being black. In this regard ANIC14 matches my specimen in having an “orange” colour throughout.
Yes a very good match incl. striped antennae & legs. There are slight variations in spot sizes. Yellow from biggest spot does not seem to continue along the inner margin to the wing base in the live specimen but it may be the way it is holding/rolling its wings obscuring this.
