Hello I been here a while and think furniture is very reasonable and found mostly in dollars what you would pay in pounds back home. I shipped my furniture all over but ended up buying mostly new stuff again once I was here. A few things got damaged in the container though and very stupidly I didn't take out insurance.
the one thing I wish I did ship before I came though was a dyson lol. They are more expensive here.
Google every day shops like Harvey Norman, Super Amart, Target.com.au, kmart.com.au, fantastic mr furniture, Big W, Adairs, Spot light and Harris scarfe, The good guys. Bunnings is b&q also to compare prices.
These are all shops you will find almost everywhere and will give you an idea of prices.
The one thing that is expensive here is food and alcohol but I don't think you can ship either lol
We shipped out all our Xmas tree, lights etc so saved a bomb at Xmas time.
Happy packing...
