Not sure what your geographical location has to do with modding.
I live in Perth and it has not stopped me purchasing kit.
The reality is unless you own a Commodore or Falcon or a popular Japanese make most of the parts for European performance cars are cheaper if sourced from overseas.
You can purcahse some things in Australia but for the cost of an e-mail you can save a fair bit of money by-passing the local supplier.
All you need to find is a mechanic to install the parts.
Hally83 has put together an excellent where/what/how on the forum if you need to get some ideas for what would best suit your needs.
Good luck,it is not hard I had never purchased so much stuff from overseas as I have in the last twelve months.
I am sure the Mrs thinks I am having a long distance relationship with the constant steam of boxes arriving from O/S
