Australia uses 240V ac mains power, so your electric tools should work fine here. Most field service vehicles here have compressors built-in,so your air tools are the best bet. Depending on the age and condition of your tools, it might be more economical for you to sell them there and replace those you need when you get here, rather than pay the shipping costs to get them here. I would certainly think hard before shipping bulky and heavy items like compressors and generators.
