95% back packer tax on Super

Hi

So it seems that the tax on people claiming their super after being here on a working holiday visa will be taxed at (up to) 95% although I have read it will probably be a little lower, than the current tax of about 38%.

I am just wondering if that will effect other temporary working visas too as the wording of the bill doesn't seem to specify visa numbers. I am here on a 457 (although spent one year on a working holiday visa) and am not applying for PR or citizenship and will likely leave at the end of the visa, but was considering super payments part of my salary and relying on withdrawing them after I leave. Does anyone know if it will effect people in my position or if people who agreed on terms before July 2017 (when the bill will officially start) will be affected

Any advice would be appreciated

Thanks
