What happens if you bring more than $10,000 into Australia?

Excuse me, could you clarify for me? I'm just curious, if someone brings more than ten thousand dollars into Australia, what would be the consequences? Is there a specific reporting requirement or tax implications? Would customs officials be involved in this process? I'm trying to understand the regulations surrounding bringing large sums of money into the country, and I'd appreciate it if you could provide some insight. Thank you for your time.
