I reported this deal earlier because the link was dead and I couldn't find the chairs when I searched manually. Manually browsing to the Outdoor Furniture category on the Bunnings website I found they are listed again but with a slightly different name. Other colors are available however only the black color is this price. edit 30/12/19 - now showing as $39 for the black acapulco.
edit just noticed this"sling" style chair is also available for $25. More comfortable looking and cheaper then anything I can see at Bunnings, Harvey Norman, Amart Furniture or Ikea at the moment. Potentially less visible steel to rust then the acapulco style chairs? Although that doesn't say anything of the durability of the textile material of the seat part itself.
If you are especially keen there is a set of 7 sling chairs and a large table for $198. Assuming the same price as the single chairs, that's $23 for the table which also seems like good value if you need that many chairs.
It somehow looks very inviting.
