Welcome!
There's heaps of places to get stuff locally. If you're after parts to source your own printer, or just want a whole kit, check out the Aus Suppliers page: [
reprap.org]
The first thing to ask is do you have any specific things that you want to do with 3D printing? I ask as not all printers can do the same stuff, so some printers won't fit your needs while others will.
Another thing to think about is how portable you want the printer? ie: do you want to take it places, or are you happy to mostly leave it on a bench somewhere.
Also think about how big an object you want to print? This determines the build size of the printer.
Lastly, are you a tinkerer and interested in the technology generally (ie: want to experiment) or do you want something that "just works"?
Hopefully from questions like these, it'll be possible to come up with some recommendations and/or so you can make reasonable decisions between a variety of printers.
