Contract or permie? Quick app to compare contract rates to permanent salaries

I've always had a spreadsheet to help me compare a daily contract rate to a "standard" salary, to ensure I'm always comparing like for like when considering jobs. A newer wrinkle has been recruiters quoting "package" salaries, which just means you need to multiply by 0.91 to get the "standard" salary (ex super). But it's always been confusing.

I've recently been sharing my spreadsheet with friends who've been considering contract jobs. The spreadsheet was fine, but a bit clunky and I'd only ever bothered to make it convert daily rate to "standard" salary.

To make this work a bit better, I created, a little one-page application I wrote to allow you to quickly and easily compare contract rates with standard salaries. It's only really suitable for Australia.

As well as nicely solving this particular problem, I also got to try out Twitter Bootstrap, which means it looks great in all browsers without me having to futz around with CSS. I'm hosting it using the new functionality Amazon Web Services have launched to allow static file hosting at the root of a domain using Amazon S3 (in the new Australian data centre).
Anyway, check out and let me know what you think.

Thank you for taking the initiative and developing this algorithm. Much appreciated!!
VERY helpful, kept looking for a tool like this. Your hard work is appreciated!
This is a great tool, thanks for making it. What does ex tax mean? Normally people refer to "before" tax. Most jobs ads have a figure that is salary only and then it says "plus super", or it has a figure that is "Including super". I don't think I've ever seen a job ad that was excluding tax. Do you mean "before" tax? I suppose it would be impossible for a company to give you an after tax figure because the company doesn't know how much tax you will have to pay because you could have other income.
