Hi Wanderer. If you're keen to enhance your garden with wildlife then, as a general principle & depending on the space available, I believe it's a great idea to plant things that are indigenous to your location. There's a number of reasons for this:
* the plants that are local to your area have evolved in association with the wildlife that's dependent on them. The two go together: local plants will attract local wildlife & local wildlife will enable local plants to survive
* indigenous plants have evolved to suit local, climate, weather, soil etc & therefore don't require the maintenance that introduced plants need. This saves time, money & energy
* humans have destroyed & still are destroying vast areas of natural vegetation & are thereby destroying wildlife habitats. Australia's wildlife is unique & its intrinsic value means it is too valuable to lose. Every bit we do to restore natural vegetation helps our wildlife to survive
* a garden with indigenous vegetation can be a seed source for other projects where it's planned to use indigenous vegetation
* every bit of restored indigenous vegetation can be part of a wildlife corridor which assists with wildlife dispersal after breeding, provides refuge in times of drought, fire or flood & facilitates natural migration. Household gardens can therefore provide these important functions in the environment
To determine the species indigenous to your location I suggest you look at your nearest patch of high quality (i.e., relatively undisturbed) bushland. I note from Google Earth that there is an area of bushland just south east of Lockyer Valley. Without a full understanding of the local environment that's where I might first look for what might be appropriate for you garden. If you need help to identify the local plant species growing there then someone from a local landcare group or an environment officer with the shire council might be able to help or point you in the direction of someone who can.

http://www.lockyervalley.qld.gov.au/ima ... ockyer.pdf has a list of some species indigenous to the Lockyer Valley. You might also try

There might also be a nursery person or local botanist who could help. The local library might have books on local plant species. Failing these sources I could trawl through my information for lists of species indigenous to the Lockyer Valley. However, although you might compile an extensive list of indigenous plants by no means all of the species will be available in local nurseries. You may have to scout around for their availability or become part of a landcare or similar revegetation project.
Of course, when planting indigenous vegetation the location of buildings, utilities & other features of the landscape need to be taken into account. You don't want a giant Queensland Blue Gum
Eucalyptus tereticornis disturbing the foundations of your or your neighbour's house.
The issue of suggestions of plant species which will attract wildlife is a little more complex than simply providing a list of species. There are lots of factors to consider & no doubt other posters will have thoughts & ideas.
