help please - Sydney area call for ID

[GregF]

Hi bat call gurus

Any ideas for an ID on the attached call?

Pretty crappy sequence, so not expecting anything definitive.  It's the only one like this from 78 calls in the data set. 

For context:

Open farmland/peri-urban habitats with weedy thickets and scattered hollow-bearing Angophora costata; in the Dural area (north-west of Sydney).

Other spp. identified - C. gouldii, C. morio, M. ridei, M. o. oceanensis, Vespadelus spp., A. australis.

Thanks

GF
