Hmmmm... I do find the idea of a "poverty line" to be very interesting.
I've planned my budget around what I would receive from Centrelink's Newstart allowance if I were eligible. It's pretty bleak, I have to say. After $150/week rent, it leaves me with $165/week.
Weekly:
Groceries $55
Transport $15
Social $30
Medical + prescriptions $12.50
Sport $4.50
Hair $2.50
Mobile $3.50
Office $8
Clothes $9
Travel $25
Needless to say, someone on Centrelink without an emergency fund or who had debt repayments would be up sh!t creek. It's well below the Melbourne Institute's poverty line for a single ($489/wk). Or for anyone who had a car. Granted, if you're on Centrelink you probably shouldn't be travelling at the cost of $1300 per year, or spending nearly $500 on clothes a year. But living on the "poverty line" of $489 per week would be lovely!
Bleak is relative. You have no job and are at the bottom of the safety net. You still have money for clothing, travel, social activities, etc. Haven't even touched on how, if this was an actual emergency, there's a lot of fat that can be trimmed. Travel, gone. Social...sorry guys, maybe after the emergency's over. Hair...I'm divided on this; my wife cuts mine, but if I was job-searching.... Sport, gone. Groceries, we spend $80/wk (plus another $20/wk on restaurants) for a family of four, so it might be tight...but that can be lowered. Mobile, that can be dropped, but not a lot I'll admit (wife's is $10/mo plus an extra dollar or two for calls made). Medical, depends on your condition I guess. Transport, only if it's for job searching. Anyways, if you have no savings and are out of a job, it's an emergency. Spend like it is. I'm fairly certain that if you cut as much as is feasibly possible, you'd have a bit left over. Build up a small emergency fund, then start relaxing a bit (bumping the social spending up to $15/wk, for example).
Oh...does $150/wk rent include utilities? If so, that's not bad! If not...then add those in. Depending on circumstances, should be possible to keep that within $50/wk. Ok, now things may be a bit tight, but not what I'd call bleak. If everyone around you has a McMansion and is spending money like it's going out of style, then I can understand you may feel like it's bleak.
