27.5 Hardtail MTB recommendations $1600 AUD

I'm new to mountain biking (lots of bmx experience) and have just moved to a semi rural area.
I am autistic so buying secondhand is a nightmare for me in terms of having to communicate and having to suss out potential issues so I'm looking to buy new.

I'm looking to use it for local commuting and some trails. I won't have money to reinvest in a new bike for a while so looking for best bang for buck.

My height: 162cm
Weight: 60kg
Bike use: Commuting (paved roads/hills and cobblestone with gravel back roads)
Some trails/jumps/pump tracks
Location: Rural Victoria, Australia (Ballarat)

I was originally looking at the Giant Talon series as there's a dealer near me but only the talon 0 has the air fork and I'm wondering if it's worth it
