So my local school chess coach said to me that I have a chance on getting a rating.

But I'm not sure if it will be like a FIDE/ACF rating or something.

But anyways are my opponents going to be harder when I have a rating?

Is it going to be good to have a rating?

Its probably a rating from just the company only I think idk.

A „rating“ is nothing. A decent rating, that‘s it.

i do not know the situation in Australia.

We have 4 types of rating.
youth
local chess club
national
fide

how do you get rating.
Join a competition or tournament with rating. The organiser of a tournament can let you know if they record the game scores for a a rating.

What do you get with rating.
Rating is estimated player level.
With tournaments most of the time you have different playing groups. f.i. Group A is for players above 1800 group B is for players under 1800.
