Thanks for everyones' opinions. I'll try answer multiple concerns in one shortish response.
Just to answer to those people saying that getting a job that pays that amount is impossible, going down the mainstream path of job finding appears apparently so but as I think I mentioned when you have close relations within a business that your whole family has a tendency of going into, it's fine.
Both my parents have worked at the same company with one still remaining as a business executive in the advertising industry and offer to give 'the kids' a competitive advantage financially/career-wise in life by trialling us with a job for six months (two have done so, I'm the last) and securing it if all goes well. Starting base of all people working there is around $70,000 with no experience whilst the median is about $200K+. The largest shareholder of the company has had two changes in my parents cycle at this place and the relations with them are great - I get to stay at their beach houses and I have visited the guy's fathers house - wow (wouldn't believe its real-estate value). Regardless I'm explaining all this information in an obnoxiously verbose way but I'm just saying it is somewhat guaranteed and I just want to find a happy medium. My brother didn't study but my sister did a bachelor of arts whilst working 5 days a week full-time and still maintained a fairly social life; I don't know any specifics but she did Arts at Monash, took about 6 months off work as a break to maintain the busy life and returned ... and that is the extent of my knowledge.
Oh and as for my saving goal over 4 years of work, it is entirely possible. I would earn $218,612 after my first four years of work after tax and I would be paying no board whilst living with my parents but I would make it up to them in later years. I'd spend around $10,000 during those years MAXIMUM on going out, clothes, games or acting out on impulses and buying stupid depreciating shieeet. Own a Kawasaki Ninja and a tank is relatively cheap for its mileage in comparison to a car and I won't plan on getting the latter until I really need one. As for inflation it's only around 2-3% each year, give or take, and at the end of that period I would put it into an IP like mentioned and start renting whilst hopefully go study abroad.
You all favoured my likely option, I just wanted an external opinion. Thanks.
