Thanks to Spikey699 for the very initial post.
This is basically the best gaming laptop under 2k right now. There have been deals with same CPU and GPU for few hundred dollars less but they don't have 144hz refresh rate nor G-Sync. If you don't understand any of these terms, I would suggest googling them.
Product - 4TK02PA (15-dc0110tx)

Also, as this is a 2018 model, it is quite future proof in many little ways
There are also GTX 1070 Max Q ($2090) and GTX 1070 Max Q + 512GB SSD ($2280) versions but they aren't worth it
You can read the previous discussions for more context - https://www.ozbargain.com.au/node/414728
I'll add more info when I think of it
