澳洲多次旅游签（frequent traveller steam）的问题

nnkk

大家好，我在immi网站自己填写澳洲多次入境旅游签的表格
但是当我选了frequent traveller stream以后，有个visa lodgement number(VLN)要我填，
详情解释是：
Visa lodgement number
Applicants for the Frequent Traveller Visitor stream or the Long Validity Visitor Visa must provide biometric identifiers at an Australian Visa Application Centre prior to lodging the visa application.

At the time of providing biometrics the applicant will be given a Visa lodgement number (VLN). This unique reference number must be entered on this form before continuing.

For additional information refer to Biometrics collection.

意思是，我必须先去哪里预定时间按指纹才能提交申请吗？

请签过的小伙伴告知，谢谢
