Ok been reading through this whole thread and couldn't help but add my tuppence worth
Firstly, as mentioned already, we all have different perceptions of what constitutes a good standard of living. We all have different perceptions of what constitutes extravagance etc etc so we all have to show a little latitude with peoples' personal accounts.
I lived in SE QLD between for almost 4 years between 2008 and 2012. I found QLD pricey compared to the UK (from a currency exchange perspective) but was able to live to what I deemed to be a "high" standard.
Now if, just if the cost of groceries in WA is 30% or even 50% more higher than the QLD, I still totally fail to see how anyone could spend $700 on a weekly shop and STILL go to bed hungry. I am sorry but most people would struggle to spend that much if they tried. Furthermore, a loo roll, one meal some snacks and milk for $200? Come one, the credibility of the problem disintegrates right there.
The first few weeks are expensive and "set up" costs can really distort the bigger picture. A joint income of $220000 is a LOT of money and even if one did manage to spend $700 a week on food AND say $750 a week on rent, there should still be plenty left. I suggest giving it a couple of months, get yourselves straight and see how it looks then. If someone can't manage on that amount of money, something, somewhere is wrong.
