Can you do a multi award booking on BA?

I am trying to get to Paris from Sydney I found a SYD LHR but would like to link the CDG to it
is that possible?
would I need to call them to do it?

BA.com website has a multi-city search function but it’s not always obvious if you’re selecting the best value flight combos.

What actually itinerary are you considering?

You could try ITA Matrix, Google Flights or Skyscanner to check the best flight/price combo and then see if you can replicate that on BA.com.
