Saving of $6,000 over 6 years equates to an average of $1,000 per year.

After Tax Income - $60,000
Less Rent - $11,000
Less Savings - $1,000

Theoretical spending = $48,000.
That's $4,000 per month in expenses.

I have no idea how a single person can spend that much.
My day to day expenses are a little more than that, and thats with a two adults and two kids (includes paying car rego / health, home, car insurance / etc).

I'm guessing he's probably paying his loans that were used to purchase cars / go holidays. But don't talk about Sydney being unaffordable if you aren't willing to make sacrifices.

Even if you wound back Sydney prices to 2008, this article would still say the same thing!
