Hi Teamfloyduk 👋 welcome back to the community! Thank you for posting.
As the community have already correctly advised you sadly can't separate out incoming calls from texts.
If you can please check out our roaming hub page for Australia here 👉 Roaming Costs in Australia | Virgin Media this should offer help and support!
Please let us know if there is anything else you need support with and we will do our best to help!
Thank you! Hope you have a lovely time on your travels in Aus! 🦘🌞
Molly
