Thanks for your feedback Marisawright and WandererReturns. I have looked at Numbeo before & will look at it again and the Aldi website. Both your observations confirm what we noticed when visiting Oz previously. We spent about a month each time touring in a campervan so low fuel costs were great. Food in supermarkets was more expensive but manageable and encouraged the sampling of lunches out which seemed reasonably priced & meant no cooking that evening! Obviously we were there in a holiday frame of mind but, coming from Yorkshire, we're always keen on value for money :).
I had hoped to buy a few clothes in Oz but found them expensive, however, I hardly ever buy any clothes at full price here, always wait for the sales & make a lot of my own having studied this at college. Going off my original topic again, I've noticed that "slow fashion" is much more of a thing in Oz. By this I mean small businesses who create, make & sell their own ranges of clothing - oh to be 25 yrs younger & this is what I would be doing. Didn't seem possible in the UK because everyone expects to pay so little for clothes - fast fashion, wear once or twice & throw away.
This is our first winter at home for 4 years & I dread to think what it will be costing in fuel to heat the house, I'm leaving my husband to keep tabs on that!
I'm off to read up on FIRB. When I looked at this a few years back, I think it was possible to buy a holiday home without being a PR but I can't really remember & it will have changed. Does anyone have knowledge on this?
Thanks again for input from everyone, all useful!
