How much money do you need to day trade in Australia?

I'm interested in getting into day trading in Australia, but I'm not sure how much money I need to start. Could you please provide some guidance on this matter? I understand that it depends on various factors such as the assets I'm trading, the frequency of trades, and my risk tolerance. However, I would appreciate a general ballpark figure to get me started. Additionally, are there any specific regulations or licenses I need to consider when day trading in Australia? Thank you for your help!
