How do I know if a R32 is Australian compliant?

[Strexx]

Do imported cars into Australia physically have a compliance plate visible? I cannot see one on the 1990 R32 I want to buy - But the car has been registered in NSW and the rego papers state "Modified as per report number HRF xxxx IP Light Vehicle Inspections" Is this compliance or should I be able to view a plate?  Thanks in advance.

Inquire from the authority who issued the permit?

There is also the 15 year rule, which sidestepped a lot of compliance work.

As above, both of my 32s were imported under the 15 year rule and do not have compliance plates fitted. What it definitely should have though is a different VIN plate attached on the firewall to covert the chassis number into a VIN, which is done at compliance when it enters the country. Should be a plate with 6U900 then the model like BNR32003105, making 6U900BNR32003105 for example.
