The graph shows our monthly spending each month since moving to Australia. I've taken out some business related expenditures that get refunded - so this is the same as the core expenditure I report in my monthly reports. You can see that the first year we were frugal and expenditure stuck around or just under the $A4,000 per month level. After that there are lots of spikes associated with travel and other larger expenditures and gradually the average has moved up to about $A6,000 a month currently. Note that $A2,150 a month is our rent. All the numbers are nominal, not adjusted for inflation.
