<blockquote rel="Santi">Hi
We're on the process of completing our documents for our tourist visa. A friend of mine who happens to vist au twice already said that i need to submit a "dummy" plane ticket confirming the date of departure to and from australia. I am hesitant to submit such fake document for it might affect the success of our visa grant once the CO finds out the real score..

I should warn you that it is very easy to check whether a ticket is real or not... If they will check and find out you submitted a dummy ticket, it could mean an immediate visa refusal and a few years of exclusion period.
Suggest you go get yourself a booking from one of the travel agencies here - they may charge a nominal fee for this though.
