Just cos they are offering a 457 doesnt mean the wages have to be so low. I mean how negotiable are they? I Wouldnt fancy trying to live out here on the lower to middle end of the scale. When you factor in buying tools etc it doesnt really leave you with a lot. I maybe wrong but i'm pretty sure there is a good few jobs out there offering more.
I work on Abernethy Road and can think of 2 or 3 places that are offering more than being advertised here
