I didn't use an agent and I got a visa. It took 6 months 1 week and 2 days to come through. I printed the forms from the Aussie Gov site and sent them in.
I would find out where you have to get your police checks from and do your meds in the area you live. Also find out how long they take to be done. You didn't say if you are going to send in forms or do you paper work online ? The later saves time. A lot of time ! Can you scan and save into folders ? If so the you could be there quicker than you think. Aussie Gov will be sending emails just asking you to email them what they want from you. Set up an email just for your emails from them any way and give it a go, and all the best.
Agents only want your money, besides from what I've read ABOUT THEM on here about them I WOULDN'T trust them to walk a dog!!
nice to see you are speaking to people that are in the same boat as you. I'm shocked that if you would of waited a couple more weeks to put in your application you could of had your visa by now. Don't worry it will all be worth it when you get here, just keep going before you know it you will be packing to leave!!.
