ANZ does not specify any minimum deposit to open a trading account. However, your initial purchase of any stocks must be at least A$500 – then, the platform allows you to make smaller purchases. Also, some assets like ETFs come with minimum investing amounts (A$500), so your flexibility in terms of purchases is quite limited. If you have a smaller budget, you may consider signing up with eToro, which requires a US$50 initial deposit, then you can trade stocks and other assets of at least US$50 per transaction or US$25 for cryptocurrency.
