I earn about $75000 and that's comfortable for me and my son, just the two of us. My breakdown is $2080 every 4 weeks rent for a 4 bed house with pool, $150 electric/month, $150 telstra/month, $800 shopping/month, $160 petrol/month, I don't have a car payment as bought it outright I manage to save a couple of hundred but as I say there's only 2 of us, no child care to pay for. Haven't had a water bill yet so don't know about that yet. I live on the Gold Coast.
