Actually those leaky artesian bores also help the survival and
reproduction of nasties like pigs and goats that destroy habitat and in
the case of pigs, are quite partial to a bit of bush meat.  Further, the
lose of artesian pressure due to the unregulated bores results in the
death of mound springs which were the pre-European source of water in
the outback.  

I think the outback birds would be better served if the rivers were left
with a fair bit of their natural flows [to fill the billabongs] and the
artesian basin is protected from over-exploitation. [The only "free"
water in Australia is water you recycle].

Other than that, there is the issue of weed invasions and the
introduction of new diseases .  There is also the impact of habitat
degradation arising through the various forms of dieback.
