I couldn't recommend a dslr personally but I highly recommend either the Panasonic G7 (which is what I use) or the Panasonic GH4. The G7 starts at around $700 aud and would still leave you with heaps of money for a microphone, cage, lenses etc. It shoots 1080p @60fps and also shoots at consumer grade 4k. The g7 is more of an entry level camera. Awesome for film making but also shoots great photos.

The Panasonic gh4 is, from what I've heard and seen, an awesome camera. My Photography teacher's son who is an indie film maker uses one, plus I've seen a whole heap of youtubers using it eg. Unbox Therapy. Its the g7's older brother and more of professional tool. The gh4 starts from around $1100aud, which will be under your budget.

I know these aren't dslrs but they are still great cameras, and highly recommend considering them

edit: you probably know about these cameras already
