UK Passport - Support Docs Question

[Bumblebee]

Hi everyone, 

I am sending my children's passport applications off and just gathering the supporting documents.This line is confusing me:

 

First British passport applicants born or adopted outside the UK – parents’ or adoptive parents’ documents - Please provide the following:

The passport you entered the country from which you are applying, and if different, any non-British passport held as well as the evidence shown in the table below:

 

Am I correct in thinking they want my OLD UK  passport that I entered Australia on 10yrs ago) as well as my CURRENT AUS passport ?  (it says for the kids if they are dual nationals to only send a full colour copy of the current foreign passport, all pages - would I therefore also only send a copy of my australian one, and not the actual current passport?)

 

So confusing!

 

Thanks for any advice!
