I'd be looking around for a private strip near home then getting the instructor to come to me. This is what aviation is actually for - overcoming the tyranny of distance.
If you really are in the stix I bet there are dozens of private strips all over and nearby work or home that you don't even know about. There are 20 active strips in the Darling Downs within 50Km of Toowoomba airport and many more besides that only get mowed when the owner needs to fly in or out. I can't imagine Victoria being any different.
If you go down this path, there are costs and benefits. Consider, it might cost a little more and require some research but you will have a greater choice of flight training facilities (Albury?) , instructors, aircraft types (as long as they are insured to land on grass one imagines), you will get to fly out of a field nearer home, make some very useful contacts and be exposed to the chance of bartering whatever you can with the land owner and possibly the other people who fly from there. Once you have whatever it takes (hours of experience) to not be a danger to your self, the furniture or the hardware you may begin to hear of flight sharing or syndicate opportunities. The big one for me - your training area will be much closer to the start of the flight and much less crowded than Sunbury.
Aeroplanes are like kangaroos, they tend to mob together. If you know where one is, I bet there's more hiding nearby.
