Can anyone suggest a subfamily for this wasp? Ichneumonidae? Light trap, Townsville, Queensland.

Hi Greame,
It looks like a female Agathidinae (Braconidae) to me. One of the diagnostic features of the subfamily is the very narrow marginal cell, ending close to the apex of the pterostigma, far from the apex of the forewing.
The forewing is very similar to those of Therophilus spp (see Fig 4D in *). This genus has a row of preapical spines on the anterior surface of the mid tibia (see Fig. 2D in *), maybe you can check if you see them?

Thers's a key an good pictures in this paper:
* Stevens, N. B., Austin, A. D., & Jennings, J. T. (2010). Synopsis of Australian agathidine wasps (Hymenoptera: Braconidae: Agathidinae). Zootaxa, 2480(1), 1-26. (PDF)

You can also have a look at this paper:
Stevens, N. B., Austin, A. D., & Jennings, J. T. (2011). Diversity, distribution and taxonomy of the Australian agathidine genera Camptothlipsis Enderlein, Lytopylus Foerster and Therophilus Wesmael (Hymenoptera: Braconidae: Agathidinae). Zootaxa, 2887, 1-49. (PDF)

Yes, I believe you are correct. Picture is of the mid tibia.

The wasp keys out to an undescribed species of Therophilus.
