DIBP processing times on their website are known for being out of date. Also they will process it when they process it. The last thing you want is to annoy the case officer and have it take longer to process.
I know someone who applied from a high risk country and I just checked my emails and her husband's visa took 4.5 months.
India website says they process 309/100 in 11 months (global standard is 12 months) and one forum member took 16 months. The processing terms is just a guide and you just have to be patient and it will be approved when they are ready.
