Do payslips need to be attested to?

I am applying for Australian immigration for skill assessment under 189 (Independent) category. The requirements ask original documents to be attested by notary public (or other equivalent). I was unsure if payslips (required to validate employment history) needs to be attested too. It seems a lengthy requirement considering five years of claimable experience working with various firms. I would therefore appreciate if user/administrator could confirm whether payslip attestation, just like other documents are required? Regards, Zain
