Joking, okay... JOKING.
Popular route is overland to Nepal (Turkey, Iran, Pakistan, India) and then ship (ie fly) yourself and the bike to Bangkok. Tour a bit in SE Asia, then make your way south, before taking another flight to Australia. It is what I did.
A carnet is necessary.
The alternative is to go through "the stans", as we call the central asian republics, into western China briefly, then drop down into Pakistan. This is a more troublesome and expensive route, but those who have done it seem to have enjoyed the trip just fine.
Most leave Europe around summer/late summer to avoid the summertime Indian heat and rain. Arriving Goa for Christmas is favourite. On this schedule you get good weather all the way to Thailand.
But this is your adventure - do it how you want. Every option and combination of the above has been discussed at length herein. I suggest you track down the talk and see what grabs your fancy.
You'll get loads of help here.
Now, it really is time for that coffee...
