dif is right.
1. press your own ammo to save $$$
2. .308 is massive. It destroys worlds. There's no need to go that big unless you want to spend $10k + on a target tacticle and split roos in half from over a km away.
3. get a .223 or a .243.
4. Tikka is an awesome brand. can be expensive
5. hit up usedguns.com.au to get an idea for what you want re price over quality.
6. Land owners get nervous letting inexperienced people they don't know on there land. The alternative is to get your r licence and shoot on state land. Hit up the game council website - it's a fairly easy test and its more common sense then anything else. You just register for spots on the website when you want to go out and your done!
7. On a side note, start reading about what you want to hunt. Do a bit of study on how foxes/deer live and how they act. I say this from experiance for walking around paddocks for a whole weekend and not even spotting anything. The little things really count, how you walk, wind direction, cast shadows, topography, the clothes you wear etc
