Looking for decent quality beer money android phone (Australia)

Looking for a decent quality beer money phone (or tablet) has to be android (not sure if a tablet or phone works better for game offers)
Did some searching and only found brands that exist outside of Aus.
If it's a phone it would need to be unlocked.
Needs to run latest android
Any suggestions for phone/tablet appreciated!

Current ideas are a samsung galaxy a12 or samsung galaxy s8.
Budget is $100-$300
