Thank you for your question, my name is Richard.
Everything I am commenting on is this Table which should be available in AustraliaClick Me
It does have Wifi, and it is completely touch screen, so works like an iPad, just bigger.
Using iDisplay, you can display the iPad on the Table, http://www.getidisplay.com/
If you want interaction though, you are better to look at an app such as Teamviewer www.teamviewer.com
This lets you use the iPad via the Table.
It is a very limited market, and currently, the only Table to consider is the one I am advising on the initial link I gave. Further Tables in Australia do not seem to be available.
If you would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
