How can we make this bushland more resilient?

As John and I moved through the bushland, chatting (as you do!) about life, the universe, we pondered how we might make this bushland more resilient in the face of climate change (I had just been reading about the work of Brian Walker, CSIRO, on resilient ecosystems).
It seems that everytime we pull a weed out, we are making the weeds in our bushland more resilient; more capable of avoiding our weeding hands, and simultaneously making the bushland less resilient, and more dependent on our weeding hands.
How can we turn this around?
