How much money can I transfer to my daughter in Australia?

Could you please clarify for me the financial limits and regulations involved in sending money to Australia? I'm considering transferring a sum to my daughter residing there and would like to know the maximum amount that can be transferred, as well as any potential tax implications or restrictions that might apply. Could you also inform me of any preferred or recommended methods for such a transfer, considering both efficiency and cost? I appreciate your assistance in navigating this financial matter.
