Boost Mobile Roaming - Lose Current Recharge?

Hey all
I am looking at the boost mobile roaming option
https://boost.com.au/pages/international-roaming

STEP 2.
Select recharge

STEP 3.
Select extras for
Intl. roaming packs

I am wondering, if I do this, do I lose my current balance of my 12 month pre-paid sim?

Thank you!

EDIT: NVM!

Thought their customer service was closed but its still open until 8pm:

"I'm glad to have you here. I see here that you need assistance with International roaming pack. I can help in getting things sorted for you today.

Please be advised that if you purchased roaming pack, you will not lose your current 12 month recharge.

The best way to purchase an International Roaming pack is through the My Boost app. Once you’re in the My Boost app, select your service and scroll down to Available Extras. You can then select the International Roaming Packs option and proceed to purchasing a pack.

You will not be able to purchase an International Roaming pack using the Recharge option on the Boost website when you are overseas. If you choose to purchase a pack when you’re still in Australia, you will be able to purchase via the Boost website but your pack will become active immediately so some of your expiry will be used up when you’re in transit."
