If for example my registration expires in June and I receive my rego renewal in the mail in May, am I able to get an eSafety check (pink slip) with my previous registration paper in say January?
Transport for NSW state that eSafety checks (pink slips) are valid for 6 months but I'm not sure if you need to wait for the new rego renewal slip in the mail.

You do not need the new rego papers to get esafety check. Valid 6 months for rego in NSW
