雇主要求TFN跟生日 - 紐澳

想請問大家，最近報稅季到了，想說跟前雇主要payment summary
所以寄E-mail跟公司要，信件內容如下:

To Whom It May Concern,

My name is XXXX. I worked for you as a strawberries picker last
September and my worker number is 11.

It is time to do tax return and I need my PayG Payment Summary from you.
Would you please send me the document to "AddressOOXX".
Or you can send it by E-mail as an attachment that would be great!

Thank you for your great help.

Kind Regards,

Name
E-mail
Mobile


而對方的回信是:
Hi, can you email your TFN and day of birth .pl
thanks


我想問的是，這樣給稅號跟生日會不會有問題
因為我也給對方我的全名，地址，Email，行動電話號碼等資料
護照號碼搞不好也有留下
會不會被搞鬼...
怕被盜領退稅或被拿去給別人當人頭戶報稅...
因為我也不確定對方是不是白工
當初雖然有給payslip，上面有寫稅前稅後多少，扣多少稅
稅後金額也有如時匯入銀行帳戶
但因沒有給super，手下工頭收押金又不退還等等情事，讓我不免疑慮
天曉得他是不是把扣的稅自己留起來沒報上去，其實是黑工假裝是白的
關於當時的事我之前有在板上po過文章，可以搜尋一下我的ID
煩請各位大大給點意見，謝謝~
