Moving abroad, new SIM , any issues?

Quick question

Son has just had confirmation of move to Western Australia for a year as part of his uni course in the autumn

He is of the generation who have mobile phones instead of phone numbers

He is born and bread in Leeds and hence has decided that 12 months of £8/month of his UK provider is dead money and so will ditch his UK contract and buy an Aussie SIM only deal as he lands

I have suggested he keeps his UK SIM going as the expense is negligible however hes having none of it

Im not sure if this is economic genius or stupidity and so opinions welcome

Young people these days dont actually use phone and texts so having a dedicated number isnt necessarily that useful when they have Whatsapp and all of the other apps they use for social media which I believe are transferable whenever you switch your SIM no matter where you live

In short if he tarts around different SIMs for a year or so is he looking at a world of pain or will his phone just quietly sort it al out?

Cheers
