which vertebrate pests are posing the most significant threats around New South Wales and why are they so challenging to manage?

I think that's a difficult question to answer because we have so many different pest animals and they all pose significant risk in different areas.

So whether it's to our agricultural industries, our environment, to our community wellbeing, feral pigs and deer have definitely, we've seen the numbers increase in recent years.

So they're becoming quite a predominant problem for some regions.

In other regions we're seeing rabbits increase and cause significant problems for our agricultural production.

Foxes and feral cats are obviously a huge threat to a lot of our small native species and so it is difficult to manage all those different threats across the landscape.

In terms of why they're so challenging to manage, we're talking about invasive species.

And they're good at it.
