Buying the iPhone 18

[u/Loud-Tell1908]

Hey guys, I'm looking to buy the iPhone 18 Pro or 17, not really picky. I'm based in Sydney but my sister is in California and we'll be seeing each other over the holidays. I'm trying to decide two things:

1. Should I buy the iPhone 18 Pro or the 17? I'm a university student, and I work at a corporate office, so that's how I'll be using my phone.

2. Should I buy it in the US or here in Sydney? If I buy it in the US, I'll be doing a click-and-collect online, so my sister just has to go pick it up. I've never done this before, so I'm also curious about the currency conversion rates and stuff.

Anyone with any insight?

iPhones in the US don’t have the physical sim card slot.
