Hi,
I have got some referral bonuses from a FinTech website/App when new Users join using my referrals code. I posted my referral code in social media groups and can see few people used it and joined the APP.
I am not an affiliate for this company and I am not undertaking this as a business activity, just posting these referral codes on my leisure time. (Similar to new people joining using your DoorDash referral link but as it's a fintech company I got portfolio units equivalent to the dollars amount)
is these referral bonus subject to tax in Australia?
