Hi Mr VS,
You don't say in which part of Australia you are located.
I'm sort of with Mr Poteroo, but then you may be able to find a 'group ownership / syndicate' in your local area.
The syndicate will have an 'economic' plan, the various maintenance and hangarage / insurance costs will be 'split' amongst the syndicate members, and your aircraft useage will therefore be a whole lot cheaper.
And you will no doubt have access to an instructor who can bring you 'up to speed' on the type - if required.
Then, if you decide that this aircraft type is not for you, you can see the syndicate about withdrawing from same.....and maybe find another, or, now that you are 'familiar' with aircraft operating expenses etc, you may be in a better position to purchase your own....and IF that is different type from the syndicate, you could ask them if they are interested in expanding the 'fleet'...??
Good Luck either way.....
Cheers
