What's your budget? In any case, if you want to play on it for 5 years, then you'll need a t least an GTX 1070, so according to the link about 2600 AU$ minimum.
Avoid the i9, it's not worth it. The chip is overheating so much it's often beaten by an i7 in the same laptop case. Most laptops on the site come with a 8750H, and you're really all set with that one
Also, does it have to be a laptop? If you want longevity and gaming performance you're better off buying a desktop PC instead, will get you much cheaper and it can be upgraded along the way instead of having to buy an all new one again.
