There are third party repair places that may be able to fix your iPad for you although if it's the digitizer or screen, it may cost more to fix than the iPad is worth.
A new iPad is around AU$500, a replacement LCD is around $35, a replacement digitiser around $25, and the tool set around $15.
The expensive part is labour. If you're willing to risk some time and money on failure you can have a go yourself, there are excellent guides online.
I have an iPad 2 that I bought new long ago and have since given to my young children. Unsurprisingly one of them dropped it and the screen stopped working. I ordered the kit, opened it up, and reseated the LCD. Would have gone flawlessly if I'd been more careful while opening it up, as it stands I now need to replace the digitiser, but it's still much cheaper than a new tablet, especially while my elder daughter is in a phase of thinking she is smarter than us and can ignore warnings like "if you balance that on your knees it will fall off and break."
That's a new iPad, not the iPad under discussion, which is worth much less. You can often buy a replacement out-dated model for around that $75 mark, and that's ignoring the time cost of trying to fix the broken one.
