Definitely a Nyctophilus, The resolution in the image is a bit low to see the required identification features. I've messaged you to see if you have a higher resolution picture.
I agree with Michael. The nose leaf does lean towards the N.geoffroyi but it is not clear enough to truly rule out a N.gouldi. Also, the tummy colouring (yellow) vs the usual creamy grey that most go with is not reliable.
