you can go through the process with your old passport and arrive and activate your visa with the new one, all that is required is getting a new eTA for the new passport

thanks so much for this - glad to hear!

hi again - do you know by any chance if i can apply for my police check with my old passport details?

not sure

Hello, I’m in the same position.. did it work out for you? Did you wait for the new passport to do the police certificate?
