Porting number to Telstra, need the old simcard?

My parents moved overseas a few years ago, I kept their number active with a $1/mth plan with TPG. They're not moving back, but have lost their TPG SIM cards.

I want to move them to Telstra now, it'll be easier to manage all the services with one provider.

During the porting, will authentication codes be sent to the mobile numbers? which means I'll need to get replacement sim from TPG first before doing the port.

Or can I do the port without going through the hassle?
