From
https://www.humanrights.gov.au/quick-guide/12091 (my bold added):
"Discrimination in employment on the basis of religion occurs when someone does not experience equality of opportunity in employment because of their religion. T
his may include being refused a job, being dismissed from employment, being denied training opportunities or being harassed at work.
Discrimination on the basis of religion alone is not unlawful under federal anti-discrimination law. Discrimination related to religion, religious conviction, religious belief or religious activity can be unlawful under the laws of the ACT, Northern Territory,
Queensland, Tasmania, Victoria and Western Australia."
And from
https://www.fwc.gov.au/general-protections-benchbook/other-protections/discrimination/religion:
"
Religious discrimination includes distinctions made on the basis of expression of religious beliefs or membership in a religious group. This also includes discrimination against people who do not ascribe to a particular religious belief or are atheists.
Although discrimination on the basis of religious beliefs is not permitted, there may be legitimate bases for imposing requirements in the workplace which restrict the worker’s freedom to practice a particular religion, such as:
- a religion may prohibit work on a day on which the employer usually operates
- a religion may require a special type of clothing which may not be compatible with safety equipment
- a religion may prescribe dietary restrictions or daily routines during work hours which may be difficult for the establishment to fully accommodate, or
- an employment position may require an oath incompatible with a religious belief or practice."
I'm no lawyer, and it obviously depends on the contracts in the NRL, but I take that to read that the NRL could not refuse Folau employment on the grounds of his religious beliefs. They could require certain conditions, as Catalans have, but you can't NOT employ someone because their religious views differ from your own. In practice I think it's a difficult situation to actually justify and prove, but in Folau's case - where the NRL basically said "his beliefs don't match those of the game" - that's pure discrimination.
