Dubai Tourist Office How Long Will It Take For Me To Get An Australian Tourist Visa When Applying From Middle East (Dubai, Qatar )?

How long will it take for me to get an Australian Tourist Visa when applying from Middle east (Dubai, Qatar )? - dubai tourist office

I am an Indian passport, I worked in Qatar for the last 5 months. I must be an Australian tourist visa request, they told me that the branch in Dubai, because you do not try to have an office in Qatar. Can someone please tell me how long the treatment to prepare for my trip? I studied in Australia and is in Sydney for a total of two years (he lived could be considered an added bonus for the visa success?). and finally, how many months the balance will be demonstrated.
Please help me with the questions above.
